Yes, sorry, I meant 1988. But I'm going to disagree with you and say Ferry did not play C that season. Brickey/Smith did.
Also, the OPs statement was that his rule "generally applies to all of our final four teams," so I did not make up the "all." And I didn't exclude Brand; I pointed out that Brand didn't meet his criteria, in an attempt to obliquely point out that "6'9 and beefy or taller than 6'9 and not necessarily beefy" seemed deliberately chosen to exclude the guys currently playing center for us: a 6'9, non-beefy guy, a 6'8 reasonably beefy guy, and a 6'7 beefy guy.
Well, you and I have been going back and forth on this one for months, and I still disagree with you. If our perimeter defense hadn't broken down in the second half we'd have beaten Kansas handily. It had little (if any) to do with their size advantage.
And saying almost all of our Final Four teams (whether it's 10/11 or 9/11) had a big center still doesn't prove anything in my mind. Eleven is still too small a sample to make any definitive conclusions, and the fact is we almost always have a big center, Final Four or not, including 1995 and 2007 and 2012. How many years haven't we had a big center since 1986? I count 1986, 1987, maybe 1988 (I say yes; you say no), maybe 1997 (after Newton stopped starting), 2008, maybe 2009 (Lance and Z each started about half the games), and this year. That's between 3 and 6 before this season, and one or two of those teams made the Final Four.
Coach K has made 11 Final Fours in the 28 years since (and including) 1986, or 39%. Two out of six is 33% (as is one out of three, if you take all the "maybes" out), really not much different. So I just don't see such a consistent theme.
