What a sad tale his life turned out to be. This could have been written for OZ. He was once one of my favorite players on my favorite team. He ended up ruining a lot of lives and then took the easy way out. I'm sure there will be lots of documentaries, books and movies to follow
Echoing a lot of what TheBucsFan said, it can maybe be summarized by saying that a good or even great college QB hasn't necessarily been trained in becoming a good pro QB. The offense run in many college programs is unlike anything that the pros run.
