fantastic hire for the Bills imo.
It is if you like:
-attention grabbing quotes from your head coach
-excitement
-players who love their coach
-an overall good (not great) defense
-inconsistent offense
-poor clock management
-highly questionable use of timeouts (Ryan frequently used timeouts when the Jets were losing in the 3rd quarter of games)
-*sideline confusion of all kinds
-a defense that will play well for almost a whole game but puzzlingly act like a sieve on a key second half drive
-a likely FG or TD allowed on opponent's final possession of first half (it seems this happened in 75% of the games the Jets lost under Ryan)
*In the 2011 season finale, Ryan was clueless to why Santonio Holmes was on the sideline late in the game. If you can find it, listen to the Ryan post game press conference or check out New York Daily News or New York Post articles from the day after that Jets-Dolphins game.
There was major confusion with the timeout called before the Smith-to-Kerley TD pass at end of NY-Green Bay game this season.
12-men on the field happened way too often under Ryan.
There was also the time vs the Chiefs when the Jets had to call a timeout after the opening kickoff.
In conclusion, Ryan is a fine motivator who players love for the most part, but there are all sorts of technical issues with the guy (clock management, timeouts, not getting the right personnel onto the field timely, etc.) that will annoy Bills fans.
Unless the Bills get a top notch quarterback and a good OC, I see Ryan with middling results just like he had with the Jets. In conclusion, based on what I saw for six seasons with the Jets, Ryan will not win a Super Bowl with the Bills if he does not develop/find a good quarterback.
