I guess tarnishing a legacy is a point of view. Some have short or maybe even weak memories, so they only remember the good. However, there are plenty of people that didn't forget how Elway screwed the Colts, or how JD Drew screwed Philadelphia etc. There are plenty of instances out there that changed the opinion in peoples minds of these athletes. For others it doesn't matter.
To me, this is not a case of player who still feels he can play and the team doesn't so he's cut loose. This is an ugly divorce with both sides throwing punches, but Favre is the one that has gone back on his word several times. It's just ugly, and it has indeed changed my opinion of him.
No, that does not take away the fact he's a HOFer, but it does tarnish his legacy in my mind, and I am sure several other minds.
