Remember, Stockton was largely a "dirty" player because, among other things, he wasn't afriad to set a rock-solid pick in the lane on big guys that didn't anticipate him being there. Fully legal and good strategy and technique, but he was labeled dirty for it.
I agree whole-heartedly that defense needs to be the mantra and I hope that Corbin is able to get them playing D and focusing on good defensive fundamentals. At the same time, if you are going to be a solid defensive team, you have to want to stop the other guy as badly as he wants to score, or moreso. Which means you will knock the guy into the bleachers from time to time.
Bottom line, however, is that when the other team is doing their best impersonation of And1 and laughing at you as they high-five their way to the bench, it is time to unload a little of that frustration on them and knock the punks to the floor a couple times. At least wipe the smile off their face while they beat you by 20+.
