well, avery bradley is probably our best athletic wing defender...I think if he plays it changes the dynamics because he can stay with a Jennings/Ellis
Courtney Lee is a solid defender, but he cant contain those guys like Bradley can when he comes back.
it all starts with guard penetration. if guards can penetrate, KG has to help leaving the paint vulnerable. Its why our defense improved so much when doc moved Bradley to the starting lineup last year in place of allen. Bradley could contain guards out on the perimeter and KG could focus on protecting the rim
