Celtics need a big who can set picks. Bass and Garnett are good; but Steimsma is horrible and JjJ is probably worse. Say what you will Kristic set great picks.
We had best pick setter in the NBA Kendrick Perkins. Perk literally swallows defender. How did you think KD and Westbrook get wide open shots in PnR?
Because, as much as I loved Perk while he was here, he always sets illegal picks.

Great example is that regular season win over the Mavs, where KD launches a three from way beyond the 3pt line to beat the buzzer. How did he get so open? A 100% dirty pick set by the beast from Texas.
Which was fantastic when he was on the celtics. Now that he's moved on, I can admit to things like that.
