Lots of mentions of Bills in the article and I agree with most of concept - teams mostly overpay for free agents. Other teams players look like treasures:
Last year Mario Williams sat in Buffalo, delaying his press conference, trying to be convinced that Buffalo is where he belonged -- and after being given $50 million guaranteed he went ahead and accepted that plight, and was a passenger for much of the year.
The Saints and Bills were at the top of the NFL in terms of committed cash -- i.e., actual money spent on salary for 2012 -- and where exactly did that get them?
In terms of pass rushers, Williams was a bust. And the Bills also went hard after Mark Anderson, aging and beat up, and he could not get on the field.
Best FA pickup by Bills recently? Probably TKO. Worst in recent history is probably OL man hired from Washington - he really did not seem to want to play.
