Boxing champ Floyd Mayweather says he believes Antonio Brown is ready for a return to the NFL -- so much so, he's willing to put his money where his mouth is. Mayweather is offering the team that decides to take a chance on the troubled 33-year-old $20 million if recruiting Brown doesn't work out. "I think AB is really misunderstood," Mayweather says. "He just wants to be treated fair. And this is for any team that's watching right now. We'll make them a deal: if they sign AB and AB go through the whole season, no problems at all, and then they gotta give us $20 million. But if he mess up, then we've gotta give them $20 million. So if any team want to match that, you know, reach out to us." Brown has had a troubled history in the NFL, leaving the Tampa Bay Buccaneers by storming off the field while throwing parts of his uniform into the stands, and getting released by the New England Patriots amid assault accusations.
