I think experience is a little overrated, on the whole. I think if you're talented enough, that surfaces to the top and factors in the most in terms of how good you are and how many minutes you'll play.
It could end up being that the guys sitting out this year are more talented/gifted overall than the three incoming freshman. If the 3 transfers have a better year than the 3 freshman next year, will it be because they have more experience? Maybe, but I'm inclined to think it would be because they are more talented ball players overall.
