We've done remarkably well in retention. The only starter-worthy talent we have lost in the last several years was a 5th year guy that went to Virginia to play for his Dad's best friend and a guy that went on to be one of the best players in the nation for a final 4 team. Is it Athens, is it Boals, dumb luck? Probably all 3.
It's all 3, but it all starts with a HC with a vision and who establishes a culture.
He recruits guys who fit that culture, and part of that is guys who buy in to the team/family.
Throw in a beautiful campus, some decent success and a little luck and you have what we have.
Be grateful we have Boals!
