John Schuhmann has an interesting article about the PnR using advanced stats.

He goes into depth about the Wizards Pick and Roll. Some interesting conclusions:
"Heading into Thursday’s game, Wall and Gortat had run almost 200 more pick-and-rolls than any other combination in the league. They’ve been a pretty solid combination, with the Wizards scoring 1.06 points per possession when the pair ran a pick-and-roll."
"But there’s a big difference between a Wall-Gortat pick-and-roll and a Wall-Nene pick-and-roll, which has produced just 0.85 points per 100 possessions."
"Wall has been more likely to pass to Nene than Gortat, but that hasn’t been a good idea, as Nene has shot just 16-for-48 (33 percent) on those plays."
"The Wizards will miss Nene, who’s out six weeks with an MCL sprain, but mostly on defense...Offensively, they’ve been a point per 100 possessions better with him on the bench. And their pick-and-roll game might actually get better in these six weeks without him."
