You will never make it to D.II unless you have a Center with at least 16-17 ID
Interesting. I could have sworn I spent 5 or so seasons in D-II before deciding to tank. Never had a 15+ ID that whole time except for one season in D-II (and I didn't do particularly well that season). There are many ways to win...you don't need monstrous ID guys to make it happen.
I always find "I did" to be a most satisfying answer to "you can't."

The thing I will add that may be more important as well for the higher OD variety big man is RB. The game I got run out of the Cup (on a -2 effort on the road, but still) my defense was pretty adequate in terms of the first shot, but because of the CT and massive rebounding edge (they rebounded more of their misses than I did!), there were a metric buttload of followup shots where Gigantor the Dunkinator stepped on my guys and either scored, drew a foul, or both. It would be interesting to see how the responses in the thread would be changed if instead of 33 points for three skills, it was 44 for those three plus RB.
