Changing Gears In The Spurs Pick-and-Roll
(UPDATE 4/22/14 - for comparison, I looked at Wall and Beal's "one speed" attack here)
But Parker has the nous to vary the speed at which he comes off the screen in a pick-and-roll, which does several important things. First it gives his big man, whether Tim Duncan, Tiago Splitter or Boris Diaw, time to set a solid screen before rolling.
For example, in this simple looking PnR, Parker's patience allows him to let the play develop by not trying to turn the corner as fast as possible:
But this would essentially leave Duncan trailing the play and not really a threat to do anything besides shoot a 17 footer. Which is ok, but for a truly elite offense, you are looking for more than that early in the shot clock. Instead, Parker knows that Duncan set a solid screen on Devin Harris, so Parker will have the edge to the corner even if he delays for a count or two. Which he does:
Parker has actually veered slightly away from the basket which does two things. First it allows Duncan to be "ahead" of him on his roll to the basket and second it forces Wright to come higher up the floor and choose between containing the Parker drive or recovering to Duncan's roll. Note that Harris is still trailing Parker because of the good screen Duncan set. This allows Parker to now turn the corner:
Wright is forced to or at least chooses to contain Parker, leaving Dirk Nowitzki 1-on-2 with Duncan and Diaw, allowing the drop off to Duncan for the layup.
Similarly, in this gorgeous play, Parker's unhurried style allows for an easy passing angle to Diaw for the roll to the hoop:
And, since Parker is taking his time and allowing his big man to set a hefty screen, if no easy passing angle develops, he can still oftentimes turn the corner and get to the rack himself:
Parker reads that Wright is dropping to cover Duncan's roll, and he uses not only his extreme quickness, but his ability to change speeds quickly to get by Harris to the bucket. Note especially his subtle fake like he's going to pitch the ball back to Diaw for the wing three which causes Harris to rise out of his stance just enough for Parker to blow by:
That play shows the importance in attacking doubling schemes to actually make both players assigned to the ball defend the ball. Here's another example, in which Ginobili does not bail out Dallas's ICE coverage, instead making Shawn Marion and Nowitzki cover him:
