They are putting out some really good offers. Holtz has a decent name, decent success. I'm guessing (like UC), most top kids won't buy in until they see it on the field.
Vannett has over 30 offers, so just trust me that his list is impressive. He's a junior tight end that's 6-feet-6 inches, and 230-pounds, so it seems pretty natural that he has so much interest. The fact that he's that big, and boasts a 4.8 forty time is pretty impressive.
There have been rumblings that he already committed to Ohio State, which he denies. Sometimes where there's smoke, there's fire, so I wouldn't get too excited about this one.
