the window of opportunity in the nfl is quite small, especially at running back. when comparing last year's class with the potential class this year, including the standout juniors, i think walker took a calculated risk that his potential to be drafted and make a team was greater last year than this year regardless of competition at notre dame. he crapped out on the draft, but hopefully will succeed in making a roster and getting a chance to prove himself. as for his degree, he can come back to fulfill the requirements, which all indications point to him taking this course of action. as long as he does that, i can't blame him for grasping at the brass ring of pro football. good luck to him.
