I am ready for some science on the measurable effects of energy budget size accruing from long term play of 7-8 vs. 10 man rotations.
What I suspect happens is that against lesser teams, rotating 10 is a big edge, because all 10 are as good or better than the opponents 10 or less.
But as the talent of the first 7-8 spikes up, the teams rotating 10 suddenly find their second 5 uncompetitive and so have to play their first five sharply more minutes. But the starting 5 is not ready for the increased minutes and fatigues.
So when Duke and UK had their long stacks they were able to stay long bench and it was such an advantage, even playing green OADs, that both made deep runs against 7-8 rotation teams.
But under short stacks, then the old dynamic of the 7-8 rotation prevails over 10 man rotations, because against to good teams the 10 rotation teams have to reduce to 5-8 to stay competitive. In turn, their 5-8 not used to going 38-40 crack.
