None of those offers are overwhelmingly impressive, with the best being Xavier and Mizzou. Temple isn't bad.
Texas Tech hasn't had a winning record in conference play since Bob Knight stepped down. They haven't won more than five conference games since 2007-08.
Providence was arguably the worst team in the Big East. BC has had three straight losing seasons and wasn't anything special for several years before that. Northwestern has NEVER made the tournament. And Iowa? Well, you've spent all day making it out like Iowa will offer anybody, since they have so many scholarship guys who wouldn't play anywhere else.
I never said they were impressive offers, they are just impressive compared to the other guys I mentioned
