With Peterson's poor play and this year's improvement albeit marginally; I am surprised he is getting as much playing time as he does.
I'm not sure what the coaches see in him. He has average hands at best and even below average on too many occasions. He is an educated man but it's not helping his pass catching abilities. Maybe he should read a book on how to catch. I don't think he should be starting. A fair back-up because he is Canadian but not a starter.
On the other side is Powell. This guy has been another bust for the majority of the year. He was a free agent from BC and BC didn't try to hard to resign him; they knew that he wasn't good enough be on the front lines.
I think Powell has been the bigger problem between him and Peterson. If your receiver is beat you have other people to throw the ball too. If your tackle gets beat your quarterback usually gets crunched.
The offensive line has been a real problem this year, second only to Maas' poor play. The last couple games the O-line has been better under the tutelage of Coach Salavantis but Powell is still the weakest link
