A friend of mine who is not on Rivals pointed this out yesterday. Perhaps it has already been mentioned here. While at Vanderbilt, Gragg was a member of the Kappa Alpha Psi fraternity. I realize that Wikipedia is not thoroughly vetted source for information, but a quick search shows multiple references to "beating pledges" and other intense hazing. I believe Kappa Alpha Psi is one of the fraternities that has used a hot iron brand on members. My friend and I both wonder if his KAP experiences may have played in role in how seriously Gragg took these allegations, or even prior rumors about hazing if he heard any.
