I think Merf got those sorts of bigs into Evansville, of all places. Its not impossible. Our problem it thinking a big must be quick enough to set high screens, then jump back quickly enough to get a board, or jump out on a defender (because our guards are going for steals) and getting back to cover their guy. It's a system that needs an exceptionally rare big (much like the exceptionally rare left tackle as described in the "Blind Side") We need, at least, another POB with great height and length, and/or hyper strength and athleticism like Zach.
WE is hyperathletic enough, but I do not think he is designed to be hyper-strong. SS has adequate slow strength, but is not athletic.
I wish we could design a system that actually used our bigs strengths instead of forcing them into an impossible mold. I almost wonder what head assistant EB is now thinking that he is the "bigs" coach?
