I do know what the statistic is, which is why I posted that. That is the statistic. I looked it up earlier in the year when we had this discussion and posted it then, so I recall it.
You mean this statistic?
STATS LLC. - there have been 981 third time matchups across Division I college basketball over the past 10 seasons. The teams entering the third game 2-0 are a combined 710-271 (.724 winning percentage) in the third meeting.
I just don't know if they define "equal" teams, if so how they do, or even how I would. I assume it is not uniformly 73% without regard to any other criteria selected.
