Barack Obama enjoys watching football, but admitted he would have reservations about allowing his son to play, if he had one.

Obama admits some of those changes might make football, in his words, "a bit less exciting" but that it will be much better for players.

"And those of us who are fans maybe won't have to examine our consciences quite as much," he said.

Obama has greater concern for college players.

"They can make some of these decisions on their own, and most of them are well-compensated for the violence they do to their bodies," Obama said of NFL players. "You read some of these stories about college players who undergo some of these same problems with concussions and so forth and then have nothing to fall back on. That's something that I'd like to see the NCAA think about."
