Nah, you don't pass up on strong talent for that justification. If PATFO cared so much about three-point shooting, they shouldn't have put this team together. No matter what, Beli and Bertans aren't getting higher in the rotation without tremendous improvement. If you can turn them into a better player who also shoots well, you do it. These aren't super two-way guys we're talking about here.
I don't disagree about adding more shooting or at least getting the guys in the rotation to be better in that regard. I just don't see how Murray/DeRozan/Aldridge/Poeltl can work together for long stretches, even if Murray's shot is improved and Forbes starts. They need a defensive four who can shoot. Some of those guys are available in trades or for the MLE. I hope they get at least Singleton, who's been a terrific shooter in Europe and a bulky defender who might play some five if he comes over. But keeping two of their worst rotation players just isn't an option unless they simply don't want to win.
