Well, when we get murdered in the paint come playoff time by Bynum, Gasol, KG, Perkins, Howard, etc while any player (even PGs) guards Bonner at the 3pt line and renders him completely useless, I hope Popovich doesn't regret not giving Splitter some PT to see what he's got.
I already know that Bonner chokes in the playoffs. Doesn't the saying go: Insanity: doing the same thing over and over again and expecting different results. Look at the Boston game - a big, important game with possible HCA implications - Bonner 30:17 mins - getting abused by Davis. Meanwhile, Dice with a smooth jumper just a few feet inside the 3pt line and much better defense gets only 14:53 mins.
Neal's gotten his chance and proved to be a big difference. Does it hurt to try Splitter - especially when he's the only one other than Duncan with size and length? C'mon, he's not a rookie out of high school/college.
