You've brought up a couple three seasons that may legitimately refute my argument. I haven't gone back 40 years to do any research on my view, but only from my memory and how just about every season it seemed that we really never have a deep bench where a number of guys coming off the bench were seeing any meaningful minutes and/or contributing.
I really don't recall ever having 8 + guys in a rotation playing more than 10 minutes a game, certainly not in conference play or tourney time. You mention Southerland and Mookie in '12, but they rarely played any minutes of significance come conference play, tourney time. When I say 7 guys, I mean 7 guys playing legitimate minutes, and not against the cupcakes in Nov. & Dec. For years it seemed to be a debated discussion...where was Tony Scott, LeShaun Jackson, Richard Manning, Glenn Sekunda, Keith Hughes, Earl Duncan...why aren't they playing, etc., etc. :noidea:
Edit: Quickly did some research, but only from FF in '87, 96 & '03. As Jack Hall mentioned above in '03 we did play 8 guys and 8 of them played a min. of 10 minutes. In 87 we basically played 7, Stevie Thompson seeing 10 + minutes but Brower under 10, and Harried 2 and a DNP. In 96 only 7, J.B. Reafsnyder saw 10 + minutes, Junulis under 10 minutes.
I guess the overall point I was attempting to make, is that over the years, generally, JB rarely plays more than 7 guys legitimate minutes when it matters most...conference and tourney play. And, consistently, he most always plays his starters 30 + minutes game in and game out.
