High School was a kid named James Banks here in Indiana. He won Mr. Football in 2001 playing for Ben Davis High school in Indianapolis. He went to Tennessee, but had off the field problems and never quite panned out. He was their QB/Safety/KR/PR/Punter. I remember the year they won state. Against Warren Central in the regional final the punt flies over his head all the way to his goal line almost. He ran back and got it then proceeded to make all eleven Warren Central players look foolish on his way to the end zone. It was crazy I had never seen a high school highlight make ESPN top 10 plays until that one.
College I would have to say the most electrifying guy I ever saw live was Warrick Dunn at FSU. Especially against the U and Florida. In college he was a bad boy.
Pros I would have to say Barry Sanders. He was my favorite player growing up and was the reason I found a love for football.
