In the 2009 playoffs,
Williams: 16.3ppg, 3.2rpg, 4.1apg, 2.1 tov, 0.103 WS/48, 107 ORtg, 53.0 TS%
Billups: 20.6ppg, 3.8rpg, 6.8apg, 1.9tov, 0.249 WS/48, 135 ORtg, 66.4 TS%

Lebron and Billups should have no problem co-existing since they actually played with teammates who attempted even more shots:
Melo: 20.1
Lebron: 19.9
Mo Williams: 13.9
Billups: 12.3
Do the Cavs have a chance of winning the championship in 2009 with Billups instead?
