She's only done that once, in 2016. After almost losing to Green Bay, she got lucky by getting the weakest 2-seed in ASU (admittedly we played fairly well, but got lucky in that ASU was the weakest 2-seed and the best matchup for us that tournament out of the 2-seeds) and going against one of the only other coaches in the country who is better at her at squandering talent in Kevin McGuff and Ohio State, who was the most talented team in the country that year but only a 3-seed. And then of course we got slaughtered in the E8 like always. Honestly the wins vs. ASU and Ohio State didn't really mean a whole lot. TN is judged on FF appearances, not getting to the E8 and getting blown out by a team you beat earlier in the season.
So yes, it could happen, but history says it won't. Otherwise, we lost to a lower seeded team in 2013 (had a prime opportunity to get to the FF when Baylor got beat), 2014 (blown out by Maryland) and last year (first loss ever in the NCAAT at home), choked a game away vs Maryland in the E8 in 2015 and didn't even score 50 points after we nearly choked to Gonzaga, and never really were in the game against LVille in 2017, a year in which we were arguably overseeded.
Honestly I can only think of two games in the NCAAT under Holly where we have played well, and that was against Oklahoma in the S16 and the aforementioned Ohio State game. We had played very ugly against Oral Roberts and Creighton (at home) in the games prior to that. In 2014 we played ugly against NW State and St John's (again at home). In 2015 we squeaked by against both Boise State and Pittsburgh (again...at home). Barely beat Green Bay in the first round in 2016, but admittedly played better against ASU and played very well vs Ohio State. In 2017 we squeaked by vs. Dayton before flaming out against Lousville. Last year we played well in the 2nd half of the Liberty game after sleep walking through the first half at home.
