Okay, I am trying to figure the math in your quote. By my count, since 1990, the SEC has won 13 national titles in baseball. I see no other school that has won the CWS in 1990 or beyond that later joined the SEC (Texas and Oklahoma pending). I guess whomever wrote that original quote is counting Missouri's 1954 title?
What I find even more confusing is the number of 18. By my count, the SEC had a team finish runner-up in Omaha 13 times. I am counting conference membership at the time the CWS took place, so I am not counting second place finishes by South Carolina in 1975 and 1977, Missouri in 1958 and 1964, or Arkansas in 1979. I presume that is what the author of that quote is doing since that would give a tally of 18 second place finishers.
I had never really looked at past CWS results in this way, but strangely, the SEC's first baseball title was in 1990 when Georgia won it all and only two of the second place finishes came before 1990, Tennessee in 1951 and Alabama in 1983. Kind of surprising, at least to me, that there was so little baseball success in the SEC for so long. I mean, it is not like baseball just all of a sudden arrived in the southeast.
Also, fuck these people that retroactively claim titles and appearances. Must have been an aggy that wrote the original quote.
