Here’s your list of players currently in the playoffs that averaged the most turnovers per 100 possessions (same thing as touches) during the regular season:

• Only counted players that played at least 24 minutes per game.
• Basically, when Reggie Evans touches the ball he turns the ball over an astounding quarter of the time.
• Obviously, the vast majority of these players are post players — and that’s the tradeoff of getting a post shot: you get an easier shot (compared to a 18-foot jumper) but the probability of getting the ball poked away is greater.
• Houston is the only playoff team with two players that averaged more than 13 turnovers per 100 possessions apiece (though Jeremy Lin is currently injured).  This turnover rate is also tempo-adjusted (i.e. per 100 possessions) so even after accounting for Houston’s fast tempo they have two turnover-prone players.

I also looked at guards that are currently in the playoffs and who had high turnover rates during the regular season:

• Again, only looked at regular season guards that played in at least 30 regular season games and play at least 24 minutes a game.
• Note that both of the Rockets’ starting guards (Lin and Harden) had high turnover rates — think how good the Rockets could be if they kept their turnovers down, even a little bit?
• Surprising that Andre Miller and Mario Chalmers had two of the three highest turnover rates of any playoff guard.  Understandably, Professor Miller runs a high-octane offense (though again, turnover rate is tempo-adjusted) that focuses on pounding the ball into the paint.  And as we saw in the previous graph, the players with the highest turnover rates tend to be post players, so trying to feed the post can be a risky strategy, which might be why Andre Miller has a relatively high turnover rate.

The statistics back up the eye test — Brandon Jennings has been able to penetrate when one-on-one against Chalmers or when BJ3 runs the pick and roll with Ilyasova.  Now, admittedly there isn’t a large sample size here, but it will be interesting if Miami puts a different defender on Brandon Jennings or if they semi-double team Jennings, because he makes up a large bulk of the Bucks’ offense (in Game 1 Brandon Jennings accounted for roughly 30% of the Bucks’ points).
