That's the debate. Everyone is going with replace Plumlee. If you are talking second unit size. That's an easier fix for sure.
We know they don't want to mess with the starting roster, YET. If we get destroyed by the other team getting tons of offensive boards each game, we will have to add size, BUT the Suns seem reluctant to move Beal, or anyone to the second unit. We have a stalemate. It may be that we need a big PF /C more than a third guard. That will be harder to do.
So the question is, do we need size with the starters? Or are we just talking second unit big?
