Outside Isolation... meh.
It seems to work like a poor man's Patient when I've gone that way. I haven't done a real data analysis, but it seems to me that the shot distribution concentrates with one outside offensive player more with Patient than with OI, and I don't recall seeing any real difference in shot efficiency between the two offenses (other than I think I lost most of the games when I've run OI). (And don't get me started about Inside Isolation, which I think means the guards get most of the shots based on the times I've tried that...)
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
