What I'm taking out of this isn't so much that Malone isn't so much saying "I think Cousins can be a defensive anchor" but rather, "If you are going to be my center, you're going to have to play defense like a center"
I think I'm starting to get a feel for what the new front office is going for here. They just inherited a team with a lot of talent that didn't fit. The moves that have been made so far have been for guys that in theory fit their positions. Their new point guard plays like a point guard, the new shooting guard plays like a shooting guard, etc. There's been a problem in this organization that there was no other way to acquire talent than to take the risks that most other teams wouldn't. Tyreke was hugely talented, but it made it important to have the exact right fits around him to cover for the things he couldn't do, that's why he fell to us I the draft. Cousins is as talented as anyone to have ever been a king, but his talent comes with its caveats, that's why he fell to us.
Bottom line what this tells me is that the new regime likes Cousins, hopes he can be the franchise center, but aren't that interested at this point in catering to him until they go through a season with him. They would rather put the effort into making him passable as a defensive center, similar to what Vlade was, than having to find the rare shot blocking, lane clogging power forward to put next to him, unless of course his other talents make it worth it
