.1st bold - too early to tell, I think
No it isn't. Even if Ross becomes a good 3+D player... those guys can easily be had in free agency or via trade. It's pretty damn near impossible to get a center with Drummond's physical tools and skill. In fact at present there is only 1 other one in the NBA.
2nd bold - not really, since the team would really only ever be able to have one of them on the court at a time, which is an issue that gets magnified when you consider the league is going small and becoming more wing-dominant
This is absolutely untrue. Please explain to me how the Lakers won the title with Pau and Bynum up front? Both of these guys were centers before coming together and are less mobile than both JV and Drummond, just absolutely 100% incorrect.
During the draft, when the Raps pick came up and Drummond was still available, I was hoping for them to trade down a couple spots to pickup an additional asset (even just adding an additional 2nd round pick or improving their own). I figured they'd still be able to get either Ross or Lamb in such a scenario. I believe BC has since said he did pursue such a move, but would have moved down to after Houston's earlier pick and feared none of the wings he liked would have still been available.
I agree that we at least should've done this but we didn't. I was still really confused as to why we didn't just trade down with Houston (8 for Lowry and 14), let them get Drummond, take Ross at 14 and still keep our 2013 pick. Oh wait I know why, it's because Nash was the first option at PG and we only wanted Lowry AFTER striking out on him.
