In addition to the fga breakdown by "play type" shown above, NBA.com also has separate "player tracking" stats that track a player's movement - one of the categories in the "player tracking" stats is DRIVES (http://stats.nba.com/tracking/#!/player/drives/?sort=DRIVE_FGA&dir=1), defined as dribbling from outside 20 feet to inside 10 feet.
The data shows that Westbrook took 376 fga's from drives.. Now here's the rub - the only categories in the fga breakdown above that could possibly include drives are "ballhandler on screen roll" and "isolations".. So what proportion of the 376 drives fall in the "ballhandler on screen roll" category - essentially, how many of the 376 drives uses a screen??
Let's conservatively assume that 100% of Westbrook's 206 isolations were drives that DIDN'T use a screen - when we subtract the 206 from the 376 total drives, that leaves 173 drives (45%), that used a screen.. And we KNOW that Westbrook pulls up for a lot of jumpers, so probably half of his isolations weren't drives, which would increase that 45% number much higher.
So there - we've just proven that today's best penetrator uses a screen for at least 45% of his drives, and obviously much more than that.. And we know WHY today's player uses a screen so much - it's because screen-roll/drive-and-kick is the primary option for today's teams, since that's the most effective method of generating the most 3-point looks.
