Someone was asking for this earlier about WCS on/off... Well, he's been a +/- superstar in the early going:
With WCS on the floor:
Ortg: 109.6
Drtg: 99.8
Without WCS on the floor:
Ortg: 98.8
Drtg: 112.1
which combines for a difference of +23.1 when Willie's on the floor. Like, that's unreal for a guy who's played more than 2 minutes on the court.
Now, this is only in 218 minutes, so the sample size needs to be addressed, but differences this drastic means WCS isn't playing nearly enough.
