Michigan coach Jim Harbaugh is never afraid to go out on a limb and propose new ideas that he feels will make college football better. His latest idea is a big one. Harbaugh said Monday during his weekly press conference that he is in favor of players being able to leave for the NFL Draft after their freshman and sophomore years, but return to school if they go undrafted. 

The NFL's current rules require players to be three years removed from high school to be eligible for the NFL Draft. 

"They can be drafted after their freshman year. They can be drafted after their sophomore year, their junior year, their senior year," he said via the Detroit Free Press. "I would also make a rule that, if they weren't drafted, they could return to college ... that would be what I would suggest and propose. And you have examples in other sports. You have hockey. You have baseball. You have basketball."
