I dont think they were that serious. Schefter said the Bills didn't think they had a decent shot at Brown and were just doing due diligence.
This does change my feelings about Beane a little bit. I do like that he was trying to get talent but going after a declining WR who is delusional is concerning in that he doesn't fit the culture and why get a guy whose past his prime when were arent close to contending. Its not like we need just one more guy to win the SB, we are in the middle of a major rebuild and the whole thing doesn't make sense.
