re: Will one-and-dones be the fall of the NCAA blue bloods?

I think it just shortens the window of time in which these teams can succeed before having to reload.

Coaches don't have time to groom these 5 star recruits to make deep runs in the tournament year after year which gives opportunities to other schools.

I think the power house teams will still remain as they will continue to attract the big name recruits. With that, that may not equal success in March.
