So history as a guide, the last time Altman NEEDED to stress "fit" over "name" he turned the roster over midseason and the Cavs were able to ride the right mix of shooting/defense/bench scoring around LeBron into the Finals. It was a very good pivot from a shoddy team built on old resumes w/talent and interest no longer there. I get that LeBron was the key to getting to the Finals, but that group had much better defined roles top to bottom than the one that they opened the season with, and it was mostly all Koby's moves that got those guys.
I'm not sold that he can do it again, but if he can, mid-season is kind of when he will need to get it done. I think the deal is a package of Rubio and/or Laurie w/either Collin, Okoro, Garland or the '22 pick for their starting SF and a lesser role player for the bench. Just my guess.
