I'm curious, do the isos look for the best inside/outside scorer, or the biggest inside/outside mismatch?
The way I've read it, it looks to get them the ball, but not in terms of running an offense to find them a good shot, instead just giving them the ball, clearing out and let the isolated player try to generate his own offense or kick it to someone cutting or spotting up. I presume with a high IS, low HA/DR/PA big man as the leading inside guy, for example, an inside ISO would be a horrible tactic - they'd get him the ball, he can't do anything but turn it over or jack up a contested low-percentage jumper.
