I agree that JP should be starting, and he might end up doing just that. But a ton of factors are influencing this decision so I wouldn't be surprised to see the Bills stick with Kelly. The fan and media pressure on TD and MM will be tremendous if the season implodes. Also with New England playing the Colts, it is very possible the Bills will only be a game back after the bye.
I'm just trying to look at this thinking about what the Bills will probably do, as opposed to what they should do. In reality with the schedule ahead we have no chance at the playoffs, but again don't underestimate just how much TD and MM are thinking about their collective heads in this decision. A 5-11 type year would be a major blow to their status with the fan base and media, and the simple truth is Kelly gives us a better chance at winning.
JP wasn't just bad for a QB, he was bad for a rookie QB. His stats don't measure up to the best post 2000 QB's, or even the worst ones. If you want so see exactly how he's faired check out this post I made awhile back, it compares the first four starts of 20 or so recent QB's. Old Post
Despite the fact that JP's first four starts are among the worst of all recent rookie QB's their is one player that JP has beaten out, Eli Manning. We absolutely must find out if JP is our Eli Manning this season, otherwise we go into next year basically in the same shape as this year, and this years QB play won't be good enough to reach the playoffs. In the end if MM and TD are confident enough in their job security, or New England Wins, JP starts, if not don't be suprised to see Kelly remain in for a few more.
