To be fair to Gailey, this is not quite an apples to apples comparison. Harbaugh inherited a very good team in terms of talent. San Fran already had a good defense and a solid running game. When Gailey came on board, what did we have?
Good lord I read this all the time, like the Bills had no talent anywhere on their roster when Gailey got here.
The Bills had Marshawn Lynch and Fred Jackson. Lynch motivated in Seattle is a 1200+ yard a year rusher along with 12 TD's and he runs like a Mack truck. Fred Jackson is like a Jaguar who is so elusive he makes the first tackler miss and breaks the second, and could easily equal what Lynch has done if he had stayed healthy. The Bills had a better running game then the 49ers
.This regime decided to draft another RB (Spiller) "waterbug" in 2010 with that #1 pick, a guy who sat on the bench for most of his first 2 years, and still isn't the starter.
The biggest problem the Bills offense was they needed a LT to replace JP who they traded away. they finally drafted his replacement in 2012 in Cordy Glenn. Why it took them 3 years, i don't know! They also needed a RT in 2010 and still don't have a top RT or RG.
For the defense the Bills have needed a top pass rusher since Aaron Schobel retired in 09. They were the #19 defense, and San Fran was the #15 defense in 2009. Jauron swung and missed with Aaron Maybin and yet the Redskins picked right after the Bills and hit a home run with Brian Arakpo. Anyway, Nix finally addressed the pass rush by adding super Mario and Mark Anderson in 2012, why it took 3 years, again I don't know
Gailey /. Nix have made a multitude of boneheaded personnel / scheme / assistant errors along their 12-24 run so far in Buffalo.
The 49ers have a great coaching staff, while the Bills have a mediocre to bad coaching staff. However, Lets not forget what Nix had to go thru just to get Chan Gailey to come to Buffalo
