With Jordan Matthews out, should we expect a step forward from rookie Zay Jones?

I wouldn't bet on it. Jones' playing time is not likely to increase with Matthews out -- expect Andre Holmes to fill Matthews' role -- so it's more a matter of whether Tyrod Taylor is comfortable throwing to Jones. The rookie has struggled to finish routes and make clean catches so far, resulting in a team-low 3.4 percent rate of catches per route run. Taylor said this week he'll continue pressing forward with Jones and keep his confidence in the second-round pick. But when the pressure mounts in games, I would expect Taylor to lean on Charles Clay and LeSean McCoy, who have proven more reliable pass-catchers. "I'm growing, I'm learning, and I know that," Jones said this week. -- Mike Rodak

What's gone wrong with Jay Ajayi so far? Can we expect a return to his 2016 form?

Ajayi is fine. It's the other players around him, particularly the offensive line, that has failed him most of this season. Teams are stacking the box and there are fewer holes for Ajayi. According to Pro Football Focus, 44 of his 46 yards last week were after contact. He is getting hit a lot at or near the line of scrimmage, which is much different compared to last season. -- James Walker
