while the Pac-10 has two. You see, it's easy to pick a random period of time to make your point.
About the SEC having 6 titles in the last 18 years you must remember 5 of those came from one school. Take LSU away and the SEC has won a whopping one national title in baseball. Now, I don't put this up to run down the SEC, but rather to show a few things. 1) That the SEC's only claim to dominance resides in Baton Rouge, LA. 2) That you can change the scenario to support your argument. The bottom line is the SEC hasn't traditionally been nor is currently the top conference in baseball. Is it tough? Absolutely. Is it a great place to play and watch college baseball? Again, absolutely. Still the Pac-10 is traditionally and currently better than the SEC.
Now I want you to contrast that with college football. Even though Bear Bryant and Bama comprise a lot of national titles, the SEC has still had 4 different teams and 6 different coaches win the national title in the same time period you pointed to for baseball. None of those coaches won more than 1. In basketball, a sport the SEC definantly doesn't lay claim to dominance in, in the same time period 2 different teams and 3 different coaches won the national title. One of the 3 coaches won more than 1. In both sports the SEC can point to numerous championships won before the era in question.
