I peaked in college.
A friend of a friend of mine has a similar story. He was the star running back of his high school team. He could litterally run circles around the other high school kids. He got a full ride to Notre Dame and was surprised that he didn't walk right into a starting position freshmen year. He also figured he would be allowed to breeze through classes like in high school. His only start in college he got injured and was out for the rest of his freshmen year. He was put on academic probation and barred from playing his sophomore year. He was booted from the university second semester sophomore year. He ended up coming to Illinois State where he got injured again, and finally got to play a little in his fifth year. More academic problems. He ended up leaving ISU without a degree and running with a bunch of thugs. I think he's in jail now.
