Those things offer no more proof than simply saying "I want to believe he is choosing us". The kid grew up an Alabama fan, which counters pretty much everything on your list. My brother has done a lot of things, but that doesn't mean I'm doing them. Some people just want to believe so strongly that they abandon reality and assign talking points that support their believe, and not talking points that support what is actually likely to happen.
This kid may very well choose UT but I'm betting it's not because of any of those things you listed. It's going to be based on which program gets him to the NFL the fastest and with the most positive exposure (like not being constantly embarrassed).
