I think Trent Edwards concussion a few weeks back cost him his ability to play quarterback.
Seriously, I think 50% of his passing yards today are to Lynch. Not that I am complaining (have Lynch on 2 of 3 fantasy teams). Nothing effective down the field, no shots to Lee Evans. The browns should be playing 9 men in the box right now.
Quinn has been effective with time. Long term, the Browns would be better off building around Quinn and the O line. I think Quinn will be effective long term with good protection, even with mediocre receivers.
