This is one of those times where you have to look at per 36 minute shot attempts. Defending a position that IT shoots less than almost all the starting pgs in the league when he often plays 8-10 minutes less than them is an argument worthy of a huge asterisk. Per 36 numbers can be very misleading but it can be useful in this type of situation so let's look at a more equalized shots ranking.
Russell Westbrook 19.1
Kyrie Irving 18.8
Tony Parker 16.9
Stephen Curry 16.4
Jrue Holiday 15.9
Brandon Jennings 15.8
Kemba Walker 15.6
Raymond Felton 15.1
John Wall 15.1
Damian Lilliard 14.7
Ty Lawson 14.1
Jameer Neslon 13.9
Isaiah Thomas 13.7
Deron Williams 13.6
Greivis Vasquez 13.6
Jeff Teague 13.2
Chris Paul 13.1
Mo Williams 12.9
Goron Dragic 12.7
George Hill 12.1
Rajon Rondo 11.8
Jeremy Lin 11.8
Mike Conley 11.7
Kyle Lowry 11.4
Darren Collison 11.0
Jose Calderon 10.8
Steve Nash 10.0
Rickey Rubio 9.6
Mario Chalmers 9.1
Kirk Hinrich 8.2
He jumps from 23 to 13 and isn't far from the top 10. When you look at that list, its obvious that the past first guys are in the bottom half and the guys that are the 1st or 2nd offensive option make up the top 10. As a pace changing sub, IT's game could be perfect for this team. As a starter I just thinks his style of play isn't a great way to maximize the other players on the team, unless we really think he's at the caliber of those other top 10 guys, especially since he is arguably the worst defender of that bunch as well.
