Offer lists can be deceptive, too. All the un/commitable offers muddy things. And it's still really early in the recruiting cycle, so a lot of kids that are under-recruited for whatever reason haven't made the camp circuit yet.
Offer lists can be deceptive because coaches tend to "group think" just like any other profession. If Saban likes a guy, you can be sure the others will take a long look.
The major point on this or any other offer given by Dooley and staff is that their jobs and careers depend on the choices they make. Thompson has a reputation as a great talent evaluator. If he loses his job because the Vols recruited poorly then his career prospects are hurt. SO..... while I have absolutely no idea whether this kid is the next great UT LB, a role player, or a scout team back up... guys whose futures depend on choosing the right recruits believe in him enough to stake their futures on him.
