I see the point of what you are saying
but think Kelly was just "reminding" people with just a few examples that Marv(and Buffalo)hasn't been adverse in the past to taking a gamble on players with perceived or real character risks.
Now this didn't happen when Levy was still coach but who can forget John Butler wooing none other than Lawrence Phillps over in Europe?

Phillips Update: The hottest property on the free agent front now is Lawrence Phillips and he and his agent are currently mulling over their possibilities. They say he may make some visits and it can take up to 10 days before we know where he will play this season. The Raiders are seen as the front runners but our Bills are very much in the picture. Like the idea or not, he is an explosive runner with more talent than Antowain Smith.
Butler in Europe? Fox Sports is reporting that GM John Butler is in Europe for the World Bowl game today trying to sign Lawrence Phillips before he leaves to come back to the states!
