Payton, his arm strength isn't there. Hes a player in decline but should do OK as a QB this year, maybe High QB2. I like Bradford as long as he stays healthy. He will start slow so you can probably wait another week or two before you put him in.
If Petyon is still looking terrible by week 4, feel free to overreact.
Our number one CB is out due to suspension and Peters is obviously a rookie. Peters got picked on by Brian Hoyer. Manning is going to pick on Peters big time I believe. I see manning having a decent day as long as he stays upright.
