At the risk of being politically incorrect, Dickerson resented a black recruiter, because he didn't want to be "the black RB". On the other hand, he resented "white coaches" trying to identify with him.
We really only had one person that he would talk to, but he didn't want anyone to know that he was talking to a "black pig farmer", who didn't go to college.
The supporter he didn't like is one of the nicest guys you'll ever meet. He asked me to go with him to meet Dickerson at Tony's in Sealy (may have been a different name then, but is Tony's now). He was pompous, arrogant, and all about the money. I was probably less that three minutes into listening and was ready to leave. The next Texas recruiter is still looking for his first friend, so he is one thing Dickerson and I will agree on.
Best thing about Dickerson was he became our recruiting poster boy against SMU. Hell, Barry would even refer to my "Dickerson letter" in recruiting for OU.
