How about head to head stats?
37 games: Duncan wins 21, KG 16 games. But with Celtics KG wins 3 of 4. Tomorrow will be 4 of 5.So teammates matters. If someone thinks that KG, Robinson, Parker and Ginobili wouldn't won titles...
In their head to head battles:
DUNCAN: 20,4ppg (46%fg,64%ft), 12,1rpg, 3,4apg, 1,9bpg, 0,5spg
GARNETT:21,0ppg (45%fg,78%ft), 11,3rpg, 4,5apg, 2,1bpg, 1,5spg
Duncan's best game vs KG 36pts,20reb,7ast
KG's best game vs Duncan 24pts,21reb,6ast,4blk
Some likes Tim, some KG. But its not Tim by a large margin...No way.
