Cousins actually, even more than Davis. We are in great need of position and raw strength. Poythress is still coping with the injury (though much better). Now if we had a healthy moose at the 4, say Gilchrist, Mashburn, Randle,Patterson, etc, then Davis hands down. However, one guy, unlimited strength, gimme Cousins.
I'd have suggested Issel, but we got some modern era bigots, so I tried to stay late 80's or better. Some names that would really contribute too would Magliore (can never remember how to spell his name.), Bowie, Nazr and the list could be long with guys that had ample physical strength. Oh, and lest I forget one of my favorites, Big Mel Turpin. Instant cinder block wall with great hands.
