lets see...
Kurt Warner left st louis in 2003 ( guess the bills were not interested).
he went to the giants in 2004. but were the giants satisfied with that ?....nope, they traded the 4th pick in the draft for the 1st pick in the draft and got some guy name Eli Manning (2 super bowls already). the bills were in a similar situation recently, having the 3rd pick in the draft, they sat still and did not make a move to address the franchise QB.
so, in 2005 Kurt Warner went to Arizona, where at that late stage of his washed up career, he went on to make the pro bowl and nfc conference championship in 2008.
Brett Farve left Green Bay in 2007.....at that washed up late stage of his career made the pro bowl in 2008 & 2009.
i guess you wouldn't even have tried to get either one.....ya know, cause it would be a waste of time trying. i'd say farve would have passed on us......but i bet kurt warner would have said yes to the bills over arizona if you showed him the money.
