UCLA Coach Steve Lavin recently said that the possibility of players leaving early actually helped him in recruiting this year. You learn to change. Duke lost 4 players off of last year's team to the NBA draft and was ranked number one going into this season's NCAA Tournament, playing a ton of freshman. Teaching in the short-term is a premium. You have to get kids ready to play at a younger age.
Talent has to play now.
It will continue. It's a by-product of the time in which we live. Give to me now what I can earn tomorrow is our creed. Kids will keep leaving early as long as the NBA keeps paying them and coaches will have to find new players. Recruiting and coaching will continue to change.
