His jump shot is improving, and he has a unique knack for back-cuts. But like Tony Allen before him, Avery Bradley gets his primary thrill from breaking down an offensive player. Demoralizing him. Filling him with doubt. Once the opposing point guard starts to grumble or panic at the thought of not reaching midcourt, Bradley gets a little thrill from the induced frustration. But there is at least one plum left that has just been out of Bradley’s reach, and it remains the sweetest fruit still on the tree. He has never forced a backcourt (eight-second) violation in an NBA game. No one ever does, of course. NBA point guards and other ballhandlers are supposed to be too quick and skilled to ever have that much trouble getting the ball upstream. But Bradley is one of the few in the NBA who applies consistent full-court pressure. Allen, now the defensive leader of the Grizzlies, is another. Bradley’s face lit up when asked about forcing an eight-second violation. It’s a nice goal. “No, we haven’t been able to do that,” he said. “We got close to it a few times, me and (Rajon) Rondo. When we drop a 2-1-2 press, a few times we’ve been close but haven’t quite got there. That would be sweet if I do get one. It’s hard though, man. At this level, it’s hard to get that count. I probably got it in college, though that seems so long ago. In high school, I got it for sure.”
