I think it can be looked at two ways a) other recruits and coaches recognize it was the right thing to do and it builds trust b) other recruits are swayed by Tajh to follow hime somewhere else.
I don't think Tajh right now is telling other recruits that UT did the right thing and they should still consider UT because the coach is honest. No, he's probably telling them to attend whatever school he's going to - think Marlon Brown. He's not looking to better UT he's looking to better his chances of succeeding somewhere else.
