I see Dummond as being better than Davis in the long run. I guess time will tell. His per 36 minutes numbers are better than Dwight Howard's during his rookie year.
Their rookie numbers:
DH: 13.2 pts, 11.1 rbs, 1.8 blks, .52 FG% with 104 pts allowed per 100 possessions.
AD: 12.9 pts, 13.3 rbs, 2.8 blks, .58 FG% with 98 pts allowed per 100 possessions.
Davis: 15.9 pts, 9.8 rbs, 2.3 blks, .48 FG% with 105 points allowed per 100 possessions.
KG: 13.1 pts, 7.9, rbs, 2.1 blks, .49 FG%, with 107 pts allowed per 100 possessions.
