I'm not sure why you'd be interested in everyone collectively agreeing on the evaluation but here's mine.
Seems like a good group and there's a lot of reasons to think they're good coaches. However, I'm personally exhausted at having a positive or negative predictions. I just want the Bills to win. I'm not going to overly care about who the QB coach is, etc. These guys, including Whaley and his staff, are the professionals. Do your job the best you can.
I'll go into the season with an open mind about whatever they do because I realize there's a lot of luck involved. I hope we get lucky with a QB and lucky that our head coach knows what he's doing.
