Veteran guard Evan Mathis is getting a lot of questions about grooming and helping young offensive linemen next to him. When he was signed as a free agent this year, we know he was charged with helping D.J. Humphries mature.
There is the potential he could also start alongside another inexperienced player in Evan Boehm, a center whom the Cardinals drafted in the fourth round.
So Mathis could be playing next to two guys who have never played a snap in the NFL. You might think he would end up having to cover for some rookie mistakes.
