Week 1 produced a mixture of breakout performers, former stars returning to glory, and monster stat lines from players who took advantage of favorable matchups.
Not all of them will be able to do it again in Week 2. Here's a look at five players who won't replicate their opening-day success.

Corey Davis, Titans (at Jaguars)
Week 1 stats: 6 receptions, 69 yards receiving
The first wide receiver selected in the 2017 draft, Davis made a couple of spectacular catches as the Titans dropped the home opener to the Oakland Raiders. His 10 targets in his first NFL game tied for eighth on the week, as he drew more looks than veterans Rishard Matthews and Eric Decker.
Now, though, he'll now be up against one of the league's top cornerbacks in either Jalen Ramsey or A.J. Bouye, and a Jaguars defense that held the Houston Texans to just 110 yards passing in Week 1. For the Titans to find success through the air this week, they'll need to spread the ball around their receiving corps.
LeSean McCoy, Bills (at Panthers)
Week 1 stats: 110 yards rushing, 49 yards receiving
Even with an extremely favorable matchup against the punchless New York Jets, McCoy recorded 27 touches, totaling 169 yards, as the Bills made it clear they plan on having him carry their offense this season.
They were also able to control the pace in Week 1, leading for nearly the entire game. Buffalo faces a much better offense in Week 2 and will likely need quarterback Tyrod Taylor to throw more than his 28 attempts from a week ago.
Carson Wentz, Eagles (at Chiefs)
Week 1 stats: 307 yards passing, 2 TDs, 6 yards rushing
Wentz threw for the third-highest yardage total of his career in Week 1 while tossing twice as many touchdowns as interceptions, aided by a breakout game from wide receiver Nelson Agholor.
The Chiefs, however, held the New England Patriots to 247 yards passing in their season opener, and they'll also have the benefit of the raucous Arrowhead Stadium crowd. Wentz averaged just 5.73 yards per passing attempt on the road last season, with two more interceptions than touchdowns thrown.
Randall Cobb, Packers (at Falcons)
Week 1 stats: 9 receptions, 85 yards receiving
Week 1 was Cobb's highest yardage total since Oct. 9, 2016 against the New York Giants. He was targeted more than 12 times just once last season.
Both Jordy Nelson and Davante Adams were targeted fewer times than Cobb, a game plan the Packers are highly unlikely to stick to. Cobb did catch 6-of-9 targets for 82 yards in the NFC Championship Game against the Falcons last season, but Atlanta has cornerback Desmond Trufant healthy to start this year, providing the secondary depth to properly cover the Packers' No. 3 receiver this time around.
Golden Tate, Lions (at Giants)
Week 1 stats: 10 receptions, 107 yards receiving, 7 yards rushing
Tate led the Lions in targets, receptions, and yards receiving in Week 1, but it was rookie Kenny Golladay and Marvin Jones Jr. who caught quarterback Matthew Stafford's three touchdown passes.
Golladay played a much larger role than expected in the season opener, and he proved himself to his quarterback and coaches, which will only lead to more playing time. Tate and his sure hands are reliable, but Golladay has a significantly higher ceiling and can make the big plays required to help keep the Lions in any game.
