5 Detroit Lions players with the most at stake in the second preseason game

Before Monday night's practice this week, and again during a radio appearance on Wednesday morning, Dan Campbell pleaded for someone to step up in the competition to fill out the wide receiver depth chart. He's basically calling on someone to perform in the game against the Chiefs, or changes may be made.

Let's focus on the two most prominent names in that competition.

4. WR Donovan Peoples-Jones

All offseason, Peoples-Jones was the clear perceived favorite to fill the role vacated by Josh Reynolds. Many Lions' fans leaned on that crutch too, most prominently to dismiss any idea of a wide receiver addition.

After calling out Peoples-Jones at one point, Campbell did say the former Brown and Detroit native has been better lately. He is the most proven of the group battling for what'll likely be one or two roster spots, but for much of camp he has looked more like a likely big-name cut.

Peoples-Jones is absolutely on the roster bubble. We'll see who, if anyone, answers Campbell's call to step up. But "DP-J" better do so, or the Lions may not waste much more time with him.

3. Daurice Fountain

Fountain had great momentum toward earning a roster spot, if not a prominent role, early in camp. But that has faded starting with the joint practices against the Giants, into the preseason opener and now through the practices since.

Fountain can re-establish himself in the Lions' wide receiver competition with a nice outing against the Chiefs. If he wants to make the 53-man roster, he needs to stand out for the right reasons on Saturday (the quarterbacking may not do him any favors; more on that later).
