State obviously would've been a bubble team at best if the SEC tourney didn't carry an automatic bid. Based on your resume and the whole body of work, I don't think they could've given you much more than an 11 or 12 seed.
UT maybe could've argued for a 7 seed, but that's about as much as they could ask for. LSU won the SEC title, but their RPI was still only in the 30s, and honestly if you look at LSU's resume based on who they beat, their record, their record versus Top 50, their RPI, etc., it looks very similar to Creighton, who got left out of the tourney altogether. They won the regular season SEC title, but still they didn't have an impressive resume, and I don't think you could argue for anything more than maybe a 7 seed at best, and you could argue for worse.
So, I don't really feel like the SEC got snubbed that bad. The league didn't deserve more than the three teams that got in this year, and you really couldn't have justified giving anyone that much better of a seeding.
