That said, Gay not coming back would force the team to be more aggressive in replacing him. Getting Bogdanovic (or someone like him) then would become a necessity for survival, not just a "next step" move. I think you still trade Beli and Bertans to make it happen, but then you split up the MLE between two players who can at least compete for a rotation spot. Maybe this is how Stan Johnson sneaks it? Him and Singleton would fill in the holes a bit, while Bojan replaces Gay.
Murray, White, Mills
DeRozan, Forbes, Weatherspoon
Bogdanovic, Walker, Keldon
Singleton, Stan, Samanic
Aldridge, Poeltl, Metu/Eubanks
Would much rather also have Gay there to push Singleton, Stan and Walker for their spots. But that could work out. The starting defense should be much better, and that bench would be fast, defensive and somewhat switchable.
