I hope i'm wrong here, but I think he's currently either 50/50 or pro auburn.
here's why, assuming he legitimately plans on signing on wednesday:
situation 1: he's sticking with UT. I think if this was the case, he would just say it. he hasnt done that so far, which makes me think he may not be sold on UT at this point in time
situation 2: he's 50/50. If this was the case, you would see him speak in ambiguities, which he has been doing. In this situation, we can assume what he's currently saying is the truth
situation 3: he's pro auburn. If this was the case, he would either say he was pro auburn (and get shredded on twitter, etc. by UT fans) or speak in ambiguities (which he has, to avoid being shredded on twitter, etc.) In this situation, we can assume what he's currently saying is not the truth, but he's simply trying to avoid the social backlash before signing day.
situation 4: i'm way over analyzing this and really have no idea what he's thinking. this is a definite possibility
anyway, those are the reasons why I think he's either at 2 or 3 instead of 1. Hopefully I'm wrong. it just seems like he would be more vocally pro-UT if he was in situation 1. He's a big need, but Butch is a good recruiter. it'll be interesting to see how this plays out
