I think we have to keep both until we see what kind of player each develops into. It's way to early to guess about where they will wind up based on what they've shown to date. At a minimum, we also have to consider the possibility that Gallo's back becomes chronic issue. Finally, Gallo is still growing and is expected to max out 1 or 2 inches taller than he is now. There is no reason he can't become a PF if he grows a little and fills out some as he matures.
