Yea, almost certainly
19 win ACC teams are the types of teams that make the NIT nowadays. What is gone are the 15-13 teams who make the field, its too tough now with the smaller conference regular season champions taking bids. For some recent history, last season 13 bids went to teams from small leagues who lost their conference tournaments, so the next 19 teams out of the field made the NIT. I think even losing the next 2 we'd be in.
What is in doubt now is a home game in the NIT, we probably need at least one more win to guarantee a home game.
