I dunno. I think it might be coincidence more than coaching. Stotts said that he doesn't value steals (which is baffling, IMO). Some of the steals last night were due to either (a) good defense or (b) sloppy play by the Pacers, rather than gambling. I can only recall two - Lillard jumping straight up to grab an entry pass, and Crabbe poking the ball free near half-court. Neither of those involved playing the passing lanes (gambling).
I really think we need to add the passing lanes to our defense - getting into the passing lanes can either result in a steal/turnover (which often leads to easy transition points), or at the very least disrupt ball movement. Of course you don't want to over-extend, but a healthy balance could go a long way towards making our defense even better and provide us with some much needed easy scoring opportunities. The best defense is to not even let the other team get a shot up!
