Certainly if you control somewhat for minutes played, Kidd's 247 minutes dominates suckmeisters like Manute Bol and DeShawn Stevenson (by the way, how is DS ALWAYS involved in "all-time worst efforts" and yet somehow hangs around? Does he have under age sex pics of someone ELSE!?!?).
Mark Madsen had a playoffs where he shot 1 for 13, but he only played 48 minutes. Erick Dampier in 2009-10 shot 0% in 118 minutes.
It just doesn't happen often that a guy shoots 12% in the playoffs and gets to play in 12 games. In fact, it has happened twice - Madsen and Kidd.
If you are looking for a guy who shot 25% or worse in the playoffs over 240+ minutes, it is just Kidd and Lindsey Hunter in 2000-01 (he doubled Kidd's shooting percentage).
Time to hang it up and focus on anger managment, Jason.
