Agree and disagree with several of your points
I'm not advocating a blow out scenario. I would have very much liked to see Fraizer go. Also, an upgrade at OC is something I wouldn't be against. Perhaps, that's a blowout situation in your mind?
Beane and McD are good at building a young team and a winning culture. Where we disagree is can they proceed to the next level? They have failed on so many levels in the post season. As stated previously, they haven't even been able to advance to an AFC title game.
Lastly, the team has continually failed to adequately upgrade both sides of the lines. Despite Beane and the Bills organization's attempts. One failure after another. You know exactly what I'm talking about. Logic tells me that they will likely have more misses than hits.
No panic here. I'm reading the writing on the wall. Don't be surprised if the Dolphins win the division and the Bills fail to make the playoffs. The Bills are in regression mode.
