A won't get you assists and it's debatable to what extent it will reduce the turnovers (which is why I replied to hrudey). It is very pertinent to this thread that HA may not be important at all while PA certainly is. There are plenty of players with very high HA and no PA, perhaps you could study those and tell us how they perform in both Ast and TOs. I will help you out, check the following who are the reverse of my player:
I think the problem I have with contributing more is that for pretty much the entire time I've played this game until this recent experimentation, I've been obsessive about making sure my guys don't have low PA or HA, and I'd always been among top two or three in fewest turnovers. Most of the low HA/PA evidence I have is anecdotal from Klein, who was 1/1. Hitchcock started 7 HA/1PA, and he's still only 10 HA/3 PA, which could lend more support to the "bad passing is bad" aspect but it a poor testbed for the other side.
The reason I mention the Princeton specifically is that the flow skills of the C in particular do tend to matter more than in most offenses. Passing on big men is extremely useful at all times, of course - the C assist to the PF for a dunk is likely one of the easiest baskets to convert. But Princeton seems to use that even more on passes back to the exterior as well as passing to people for driving attempts, which unfortunately seems to be way too frequent with a solid passing C and a guard/SF who has high driving and low IS.
