MY PRESEASON WEEK 2 TAKEAWAYS

PATRICK MAHOMES SHOWS OFF ARM; AJ MCCARRON FRACTURES COLLARBONE

It's Week 2 of the NFL's preseason as we inch ever closer to the games that count. But there's plenty to glean: How did the rookies look? Who's making a push to be a starter? Who's carving out a spot on the final 53? Here's the biggest takeaway for each team.

CHIEFS 28, FALCONS 14

KANSAS CITY CHIEFS

Late in the first half, Patrick Mahomes showed why the Chiefs are so excited about his potential. He uncorked a throw not many NFL quarterbacks could make with an over-the-top pass to Tyreek Hill that traveled about 70 yards in the air. The 69-yard TD was Mahomes' first of the preseason. But Mahomes also showed some growing pains. He threw an interception into double coverage on the previous possession.

ATLANTA FALCONS

Matt Ryan has more than enough weapons to help the Falcons overcome last season's shaky offensive output if his line holds up. In Friday's second preseason game vs. the Chiefs, Ryan found maturing TE Hooper for a 4-yard TD and hooked up with electrifying rookie Calvin Ridley on a 36-yard deep ball, all with Julio Jones and Devonta Freeman sitting out. Ridley also caught a TD pass from backup Matt Schaub. Once Ryan has his full arsenal, it could be a 30-point explosion any given game day

BILLS 19, BROWNS 17

BUFFALO BILLS

The Bills' three-way competition at quarterback could quickly become a two-man race after AJ McCarron reportedly suffered a hairline fracture to his right collarbone Friday. McCarron started and failed to gain a first down in four offensive possessions, taking one first-quarter sack behind a problematic offensive line. Coach Sean McDermott could have a looming decision to make between Josh Allen (18-of-32 for 176 yards and two touchdowns this preseason) and Nathan Peterman (17-of-20 for 231 yards, two touchdowns and one interception).

CLEVELAND BROWNS

The Browns' early success in the running game, gaining 73 yards in the first quarter, overshadowed what was an unspectacular night from quarterbacks Tyrod Taylor and Baker Mayfield. Taylor played four possessions, completing 4 of 7 passes for 22 yards, while Mayfield played from late in the second quarter until early in the fourth quarter, completing 7 of 13 passes for 75 yards.

PANTHERS 27, DOLPHINS 20

MIAMI DOLPHINS

Dolphins coaches will be upset for the second consecutive week. The biggest concern? A defense that gave up 226 rushing yards, including a 71-yard Christian McCaffrey TD run against the starters. It's worth wondering if they need to add talent at linebacker and along the defensive line. On offense, Miami continues to look undisciplined, with penalties halting drives and forcing field goals instead of touchdowns

CAROLINA PANTHERS

The first-team offense still has some work to do, particularly in pass protection after giving up two sacks against Miami. But Cam Newton, with a 58.5 career completion percentage, is showing he can be more efficient in Norv Turner's offense, and Christian McCaffrey is showing he can run between the tackles (see 71-yard touchdown run). Newton completed 75 percent of his attempts (9-of-12 for 89 yards and a touchdown) in five series Friday night, and has completed 71.4 percent in two preseason games. That's a win. Now if he can be efficient without making mistakes, as he did with his one pick.

GIANTS 30, LIONS 17

NEW YORK GIANTS

It was an evening of redemption for Davis Webb. After a shaky outing last week, he bounced back in a big way Friday. Webb completed 14 of 20 passes for 140 yards and a touchdown and played the entire first half. He showed a strong command of the offense and an ability to fit throws into tight windows. He had a QB rating of 106.3 after a 49.4 last week. This was much needed. Webb didn't play last season and likely won't play much in preseason game No. 3 next week, when Eli Manning will get his opportunity to get ready for the season. Manning didn't play against the Lions. Webb gave the Giants hope that they have a trustworthy backup in 2018 and the potential for more in the future.

DETROIT LIONS

More of the same issues that plagued the Lions last season. Detroit, for the second straight game, got no real pass rush despite the Giants sitting top playmakers Eli Manning, Saquon Barkley and Odell Beckham Jr. The offensive line (minus right guard T.J. Lang) was also 2017-level bad. Stafford was sacked twice in three series and almost every starting lineman appeared to struggle with the Giants' front. Yes, it is only preseason, but considering the Lions knew these were problem areas and they still look like problems, it should be concerning. The third preseason game against Tampa Bay will be very telling.

CARDINALS 20, SAINTS 15

ARIZONA CARDINALS

It won't ignite a bona fide starting quarterback competition, but Josh Rosen looked much more polished than he did in the preseason opener. Rosen entered the game early in the second quarter with the No. 1 offensive line still in the game, and the better protection enabled the rookie to engineer a seven-play, 87-yard drive that ended in his first NFL touchdown pass. Along the way, Rosen got help from a roughing-the-passer call and also benefited from a 40-yard pass-interference penalty. In the red zone, flags for a false start and delay of game didn't faze Rosen, who on third-and-goal from the Saints' 13 zipped a pass to fellow rookie Christian Kirk for the score. Then Rosen, this time with the No. 2 offensive line, went on to lead a drive for a field goal, and he might have run a successful two-minute drill if not for a missed 46-yard field goal try as time ran out in the first half. In his only quarter of action, Rosen completed 10 of 16 passes for 107 yards and a touchdown, along with a nifty 102.9 rating. It was a big improvement over his performance last week, when the No. 2 line struggled to protect him and had issues snapping him the ball.

NEW ORLEANS SAINTS

Veteran Tom Savage surged ahead of second-year pro Taysom Hill in the Saints' backup QB battle -- but mostly by default after Hill had an extremely rough night. Hill threw two interceptions and fumbled three times (losing two of them) while playing the entire first half. The dual-threat QB did show off his legs with a 43-yard scramble -- and the Saints likely will keep him on the roster because of his potential and his special-teams ability. But it's hard to imagine the Saints can trust Hill enough to have him be Drew Brees' backup just yet. Meanwhile, Savage also fumbled (and recovered) on his opening drive in the second half. And he has been more solid than spectacular this summer. But he had the much better night, completing 6 of 7 passes for 53 yards with no touchdowns and no interceptions. Undrafted rookie QB J.T. Barrett scored the Saints' only TD of the night on a 12-yard run with 20 seconds left. But he's campaigning more for a developmental role than the primary backup job this season.

PATRIOTS 37, EAGLES 20

PHILADELPHIA EAGLES

The health of quarterback Nick Foles is the No. 1 issue for the Eagles coming off their preseason game against the Patriots. He left in the second quarter with what the team described as a shoulder strain. He grabbed his throwing arm after defensive end Adrian Clayborn hit him misthrow from his blind side. With Carson Wentz's status still up in the air for Week 1, the Eagles need Foles to be available.

NEW ENGLAND PATRIOTS

Tom Brady, at 41, looks like he picked up where he left off. Playing six drives in the first half, he led an opening touchdown drive and finished 19-of-26 for 172 yards, with two TDs and no interceptions. Meanwhile, perhaps more promising for the Patriots was the way they won one-on-one matchups in the pass rush, specifically with Adrian Clayborn (free-agent signing) and Derek Rivers (2017 third-round pick) picking up sacks. Rookie linebacker Ja'Whaun Bentley (fifth round, Purdue) continues to make a charge for more playing time.

PACKERS 51, STEELERS 34

PITTSBURGH STEELERS

James Conner and James Washington look like the playmakers the Steelers need. Conner, who entered his second training camp in much better shape, showed off his conditioning with runs of 24 and 26 yards on back-to-back carries through the teeth of the Packers' defense and into the end zone. He has solidified his role as Le'Veon Bell's backup. Washington has a knack for the contested catches, winning twice over the top of Packers defenders for scores and finishing with 114 yards. He'll get game passes from Roethlisberger soon enough.

GREEN BAY PACKERS

On a night when a couple of veterans made big plays -- Tramon Williams' pick-six and Jimmy Graham's touchdown catch -- just as encouraging was the emergence of a couple of young playmakers. Outside linebacker Reggie Gilbert, who spent most of his first two NFL seasons on the Packers' practice squad, recorded 2.5 sacks -- an indication that his late-season promotion to the roster was the start of something big. Rookie second-round pick Jackson flashed his athleticism on a 22-yard interception return for a touchdown. For a defense in need of playmakers, Thursday's win was a move in that direction.

REDSKINS 15, JETS 13

NEW YORK JETS

Their quarterback situation is as unsettled as ever. Did someone say controversy? It was a mixed bag from Sam Darnold and Teddy Bridgewater, setting up a fascinating decision for Coach Todd Bowles at the end of the preseason. Frankly, Bridgewater looks like the best QB on the roster, but you can bet Darnold will get another chance to win the starting job. The rookie threw a red zone interception in an otherwise solid performance, but his inexperience jumped out on a few plays. Could the Jets trade Bridgewater? Anything is possible.

WASHINGTON REDSKINS

The Redskins have focused hard on the defensive line the past two years and it should pay off this season. Rookie nose tackle Daron Payne, who has drawn rave reviews in training camp, showed his power in taking on double-teams and an ability to win a one-on-one matchup for a sack. Second-year lineman Jonathan Allen also made his presence felt with inside rushes. If these two stay healthy, they will make a big difference with the Redskins' defense.
