Celtics: Jackson Jr, Winslow, Bane, Tillman, Valanciunas
Grizzlies: Brown, Smart, Williams III, G Williams
This idea is for squad depth and height. Jackson Jr injury isn't too serious and his previous growth shows the signs of a future all-star. Tillman and Bane will be great role players now and in the future and Valanciunas can be a future salary dump or a cheap physical centre and Winslow can be a bigger version of Smart without jacking up so many threes.
For the Grizzlies, Brown is locked in for the future, is a legit all-star and given how close Memphis is from his home town, I'm sure Brown would happily stay long term. Smart can counter Morant's defensive deficiencies and Timelord is a sold Jackson Jr substitute.
