5 Detroit Lions who must be at the top of their game in Week 3 vs. Atlanta Falcons

3. RB Jahmyr Gibbs

Gibbs' usage increased in Week 2, and with David Montgomery all but sure to be out he's in line for another uptick against the Falcons. Craig Reynolds is a fine player, and Zonovan Knight is certainly an interest addition to the roster from the practice squad. But it's lined up to be the Gibbs' show on Sunday.

In Week 2, Gibbs had a notable drop and Campbell blamed Jared Goff's decisive pick-6 on his having overrun his route more than Goff's throw. He has some work to do in pass protection, as could be expected. It was also odd that Reynolds took a lot of work in the Lions' backfield after Montgomery left the game.

All in all, Montgomery's absence opens up a bigger opportunity for Gibbs as the Lions' clear best running back. Week 3 won't be a referendum on him by itself. But he needs to hone some things so his talent can shine its brightest. With Bijan Robinson on the other sideline, Sunday would be a prime spot to put it all together.

2. WR Josh Reynolds

To be entirely fair, Reynolds has more than stepped up over the first two games this season. He was clutch in Week 1, on his way to a team-high 80 receiving yards. He followed that with five catches for 66 yards and two touchdowns in Week 2.

Reynolds has popped up on this week's injury reports with a groin issue, which limited him in practice on Wednesday and Thursday. Fellow wide receiver Amon-Ra St. Brown (toe; turf toe?) was back at practice in a limited fashion on Thursday, but it's fair to assume he won't be 100 percent on Sunday if he does play.

If he's able to go on Sunday, Reynolds will likely see primary matchups on the outside against Falcons' No. 1 corner A.J. Terrell and/or former Lion Jeff Okudah. His performance and connection with Goff takes on greater importance if St. Brown is out entirely, but Reynolds has to continue his nice start in Week 3.
