the concussion has nothing to do with his play, b/c he was damn near perfect 2weeks later against SD. I think your on the right track with the playcalling and tougher opponents but i think the reason is a little different.
In the third quarter of the 1st Miami game we were up by 9 and Josh Reed got hurt, and that is when Trent began to lack confidence and turn the ball over. I'll admit i was one the many who just wanted to give Hardy the nod over Reed once he was drafted, but Reed really makes this offense go with his clutch posessio.n catches, since in Buffalo we haven't played with a tight end since 2002 when Riemersma left.
Once Reed came back against KC we score 54 points, then Trent gets hurt early against SF and cant throw accurately anymore. Overall i think trent will be good but maybe not great QB, if he s surrounded by any above average line, which he's not now, and given a few more weapons, he will be successful.
Oh yeah, and FIRE JAURON!!
