For Moranis -
At center, we are going with 4 time DPOY Ben Wallace. We absolutely understand the concerns expressed by some regarding Big Ben's offensive limitations, however he is such a good rebounder and defender we think he makes up for it. There are few players in history that could alter a game defensively like Wallace could. And we will also remind everyone that Wallace was the best player on a championship winning team. There aren't very many of those players available in this draft that can say that. He consistently limited Shaq and other centers that were bigger then him, which is all we need from him. We need him to take on players like Moses while also having the versatility to defend centers like Jokic, and we think he can do both of those things. In fact, he may be the only center that can defend every other starting center in this without the need for double teams. That is where his strength and true advantage is. As for the fit between Wallace and Malone on offense, I feel I need to again state that Greg Ostertag was the starting center on the best Jazz teams and before Ostertag, Felton Spencer was the starting center. Both Ostertag and Spencer are worse offensive players than Wallace, they are also much less athletic and mobile. We actually think Wallace's athleticism, strength, and rebounding prowess will actually make Malone better.
I certainly agree with your post here about Ben Wallace but I'm having a hard time reconciling the possibility of Big Ben having to deal with the likes of Jokic, Gasol, Arvydas and even Divac for an extended period of time....
Sure - BW would mitigate the scoring and rebounding of players like Jokic, Gasol, Arvydas and Divac but he wouldn't affect their PASSING...
In a setting like THIS those four multi-faceted Centers wouldn't have much trouble getting the ball to cutters like Nash, Reggie Lewis, Thunder Dan, Roundfield, Rashard Lewis (waiting for an open three in a corner somewhere) or my Offensive Dynamo in World B. Free

This is just "MY" roster.
Jokic, Vlade, and Arvydas would have similar offensive weapons to defer to. And with these four they had decent outside shooting - especially Marc Gasol in his latter years

I'm sure you could have Malone guarding Marc on the perimeter but what about Rashard Lewis when he's in the game?
And if Ben Wallace and Karl Malone are busy on the perimeter with Marc and Rashard Lewis OR Milsap who is guarding the basket for the cutters? I know in MEM one of Marc's FAVORITE cutters was Tony Allen

For me personally I could go with Marc, Paul Milsap and Rashard Lewis as deep-shooting Bigs - ALL with the ability to shoot a decent percentage from deep without sniffing the basket BUT with Marc and Milsap especially they can score in other ways if presented to them.
Against Jokic? Jokic is IMO an even BETTER passer than Marc and Arvydas and Divac aren't that far behind at all IMO.
Again this is why I chose Marc - especially in THIS setting...he does MANY things well.
