I'm not an expert, but he exhibits similarities to all of the people I've met who are on the spectrum. The lack of social norms, the ability to hyper focus, the lack of caring about appearance, the memory recall ability. Hell I even heard a story from a Kevin Faulk interview where he didn't respond to Kevin saying good morning for 3 years as they passed in the hallway. That has lack of social cues and awareness written all over it. I think over the years BB has learned those social skills a bit more, but you can see he's only happy when talking X's and O's, football history, and fishing. I don't think he's far into the spectrum, but definitely exhibits signs.
