Wrt Waters, Edwards etc....Stevens has also (imo) done a good job collecting guys who are one question away, as opposed to 2 or 3 questions away. Waters had to find a way to hold up on D given size, shoot, score....a lot of questions. Edwards was similar.Ainge also had a lot of draftees to try to work into the lineup. Langford and Nesmith were going to get their chances to crack the rotation, and I can see why Ainge didn't want to walk away from Waters, Edwards, Ojeleye, etc. I mean, posters still bring up Max Strus as one that got away. To be fair, the players occupying spots 11-17 were not going to make up for Hayward's injuries, Kyrie's Kyrie-ness, Kemba's knee or Al Horford's exile to Philly and OKC.
Stevens knew he had to do something with the slots 6-10 during the offseason as the players occupying those spots got badly exposed in the playoffs, especially in the Finals (with the obvious note that it's the first 3 of those 5 slots that are most critical in the playoffs). And it will be nice to be able to distribute some minutes in January, February, and March, something Ime often did not have the luxury to do during last season's drive.
Hauser is nice in that there's really only one question: can he find a way to move enough on D to not get run off the floor.
