If history indicates anything, then
we have to win at least 21 more games in the regular season/SEC tourney to have a chance at a national seed.
Over the past 5 years, national seeds win on avg. 44.7 +/- 3.2 games. (Average record is ~45-13). No national seed has won less than 40 games (2 out of 40 have had 40 wins, both SEC schools; USC in 2012 & Florida in 2014). Only 1 national see lost 20+ games (Florida in 2014).
To be a regional host, we need 17 more wins. A regional host typically has 40.65 +/- 3 wins (average record is ~41 - 17). There have been a few outliers, both UCLA and Cal St. - Fullerton, host with 33 wins. I think that has to do with getting more west coast regional hosts than earning it.
If we get 38+ wins, I think we have a good chance at hosting. We really get in the national seed picture at 42 wins.
