I think what
@hoopsjock said about a need for consolidation couldn't be truer. When we just jammed a player that should play into the roster, what gets dislodged is another player. Whether it be Moe or Jake (you know it won't be ET), it's not a stable environment. This would be a reason for a free agent not to sign in Portland. For example, Jake was playing his ass off, then Moe came back and Jake didn't see the floor. That is crazy crazy. You can point the blame here or there, but it is not a good problem to have.
Besides, everyone is ALWAYS touting this continuity thing in a macro, seasonal sense. But I'd argue game to game is where you want your continuity and stability. Let guys get comfortable and get a rhythm, build chemistry. Otherwise, the are looking over their shoulders the whole time. Moe is susceptible to crumpling under such pressure, Sauce did, Zach is all fucked up. Also asking players to navigate a jumbled mass ends up being just another word for depending heavily on Dame and CJ, which we know (see 2017-2018 playoffs for example) isn't a winning formula in the postseason...
