I also proposed a trade similar to this a while back. Bender and the potential for Ingram to slip has grown on me since then, but I'd definitely consider it, especially if Ellenson is available. That right there would upgrade our front court significantly, in my opinion.
Hell, we could even do a bigger trade if we were targeting Ellenson:
Boston: WCS, #8, 2021 1st
Sacramento: KO, #3
KO would be a great stretch 4 next to Cousins, and would be much, much cheaper than Anderson. That would seemingly be a great trade for both sides.
