Last season they won 23 games and went pretty deep in the NCAA Tournament. I think they lost to UNC
To be fair, they won just 19 games in the regular season and ACC tourney, entered the NCAA Tournament as a 10 seed. After their first round loss to Pitt in the ACC Tourney, Lunardi had them in his First Four Out. That they managed to pick up 4 more wins en route to a Final Four berth and 23-win season is a testament to them peaking at the right time (and a bit of luck, see below)... but RUJMM78 was right in saying the last couple seasons, they haven't made it to 20 wins (at least, if you're looking at their season number during selection time).
Their last three regular seasons have been:
2016-17: 18-13
2015-16: 19-12
2014-15: 18-13
Edit: Also, their 2015-16 Final Four path was very lucky.... faced #7, then #15, then #11 to get to the Elite Eight. To their credit, they overcame a 16 point deficit to beat UVA before getting housed by UNC.
