Perhaps March 3, 2018 against Clemson?
In terms of regular season, I got 2 big ones with significant tournament implications. We needed both... and we won both.
- Last game of regular season 2018, Q1 win at home against Clemson who was ranked 18. Lose that one and we there was definite concern about missing the tournament. We had aleady lost 4 of the previous 5.
- Maybe the 2017 game at home against Duke (3rd last game of the season), when they were ranked #10 (Feb 22, 2017). That put us right back in the tourney hunt ... we ultimately were the last team out because we lost round 1 of the ACC tourney.
There are certainly some huge conference tournament games with tournament implications since 2016. Unfortunately we were never successful in those.
- 2016 Tuesday ACC Tourney Game against Pitt - some viewed it as a play in game. We lost, but we still got in the back door - the next 5 days were the initial year I did a bunch of bubble watch stuff, as all the teams on the bubble (and there many that year of all sorts) still had to play.
- 2017 ACC Tourney, our first game against Miami, a fairly similar level team who was an #8 seed in the tournay. We ended up losing. 2017 was a bit of a "boring" bubble and it was really only a few teams that really were serious bubble teams ... that was a huge game.
