First, Polk wasn't there in 1971. Paul Gregory was.
Second, that's not even the right year. We won the SEC, and District III in 1971, to go to the CWS for the first time in MSU history, with our pitching staff intact.
1970 was the year that we lost the 2 pitchers because they had played as freshmen. We also lost our starting first baseman and third baseman. We lost the Disrtrict championship to FSU, and they went on to finish 2nd (to USC, of course). As far as I know, this is the only time that happened to us. (Gregory must have lost a hell of a lot from his SEC championship team in 1966 to have had to start 4 freshmen in 1967.)
Polk didn't coach his first MSU team until 1976, and he did want to be Miami and USC in baseball, and the SEC did pass legislation limiting scheduled games to something like 40 games. He was fighting with the SEC before the NCAA. And by 1978, his first year to make a regional, the NCAA tourney had expanded to 48 teams. His first 2 years, and when Gregory was coaching, you had to win the SEC to make the tourney. One SEC team, not 8. Then there was 1994, when we were 15-12 in the conference, and didn't make a regional. So, yes, apples and oranges.
1985 was the only year that I thought that we really should have won the CWS, except maybe 1979 when we beat eventual champion CSF in the first game, or 1983 when we had to go to Austin for a 6 team regional and ran out of pitching after beating TX to get into the winner's bracket, and UT and Bama played for the championship. (Good chance we'd have run out of pitching in the CWS too.) The biggest disappointment for me was the '89 team not making the CWS, but that team probably didn't have the pitching to win if it had gotten there either, a constant refrain of Polk teams.
