Their PPG was due to having leftover talent from Oats and leftover tempo from Oats. As we got further from Oats, the talent and coaching that made his system go fell off. The PPGs you cited aren't impressive once you consider we were playing a top 10-20 tempo in those seasons.
We do remember things differently, because I remember sitting in the crowd wondering why everyone was standing around the perimeter instead of moving through the D. Then we'd jack a late three and pray for the offensive board. Our assist rate fell off once JW became HC, even with a very good MAC PG in Rondo. Can anyone tell me what type of offense JW ran here? Coach Jacob, here's your chance.
As the Doc pointed out, the struggles of his iso ball almost always spelled doom against the top of the MAC. As good as Jeenathan, Graves, and Rondo were at iso ball, good teams knew how to shut it down when it mattered. Also, "iso ball players" aren't only good in iso situations, so mixing in running an actual offense that gets them in advantageous situations is what the best teams do. Kobe Bryant was an excellent iso player, but he also benefitted from offensive design that got him in pindowns, post ups, downhill off screens, etc.
The offense was sustained by elite offensive rebounding led by Mballa and Jeenathan, which good teams were able to snuff out. His rosters never had enough shooting, quality or quantity. He basically tried to run Oats' run and gun dunks and 3's system, but completely forgot the most important part, outside shooting. It doesn't work without it.
His recruiting let him down in the end. I always pissed and moaned about it and they never corrected it. Quality players make everything go, or not go, in the end.
