I hate stats. So, instead, I am going to used completely arbitrary ratings of skills from 1-10, based purely on my own, unprofessional opinion, from watching these guys play.
In these ratings, 10 is best in the league at the position, 5 is average for their position, 0 is Scalabrine.
Passing: Rondo - 10, Rose - 6, Paul - 8, Williams - 9
Defense: Rondo - 9, Rose - 6, Paul - 8, Williams - 8
Long range shooting: Rondo - 3, Rose - 6, Paul - 8, Williams - 7
Mid range shooting: Rondo - 4, Rose - 7, Paul - 10, Williams - 8
Finishing at the basket: Rondo - 6, Rose 10, Paul -8, Williams - 8
Rebounding: Rondo - 8, Rose - 8, Paul - 8, Williams - 7 (yes, they are all excellent rebounders)
So, here are their averages: Rondo - 6.7, Rose - 7.2, Paul - 8.3, Williams - 7.8
And that is my completely biased and unscientific way of explaining why I will take the more complete games of Paul and Williams over Rondo's any day.
