QB and coach are really the only 2 in any game you can blame.
Heck, Saints lost to the Jets because Brees threw 2 big INTs, and on a huge drive on 3rd and short Peyton called for a swing pass to the fullback whcih failed and on 4th and short they called a reverse to the 3rd string TE, got too cute.
There you go, Saints lose to Jets. Same as this game, except the Saints get a little more of the benefit of the doubt due to past performance, Bills do not. In reality, Saints should be blasted too.
