I've been spouting off on this board for quite some time that this summer was the tipping in point in which Ainge needed to pick a direction and make the moves to hit that direction. He couldn't just keep adding top picks to the current roster and expect that to work for much longer. I'm glad Ainge finally made that decision, and consolidated assets and the roster a bit, but I would have done it differently.
After the trade with Philly, I would have packaged 3, Crowder, and filler (maybe Zeller) for Butler. I would have then moved Bradley, Smart, and the Boston 2018 1st for George. Since the cap space was gone at that point, I would have kept Jackson and re-signed Olynyk, Jerekbo, Green, and Johnson. I probably would have still looked at vets for the MLE, like Baynes, but would have been ok just filling out the roster with young guys.
So I would have entered the season with
PG - Thomas, Rozier, Jackson
SG - Butler, Green
SF - George, Brown, Nader, Ojeleye
PF - Johnson, Jerekbo, Yabusele
C - Horford, Olynyk, Zizic
