Ainge probably could have made a trade before the season like KG for Hedo Turkoglu, JJ Redick, and a first round pick, getting the Celtics both a young player and a pick in exchange for taking on a bad contract.
Maybe the Celtics should have offered Brandon Bass to the Lakers in exchange for Luke Walton and a first round pick.
Maybe that should have been Ray Allen to Indiana for a mere second round pick or maybe two second round picks (but not a first).
