Of course it is possible. Is it likely? No.
What are some crazy team sports miracles in a series (not a single game) that would make us believe that maybe, just maybe the Dukes could pull it off?
Keep in mind that no team in the CAA has ever won 4 games in 4 days coming out of the Keener/Rowe round. Of any year for it to happen, this would be it with the best team being ranked #123 nationally.
BTW, The worst record to ever make the NCAA tournament is a 3 way tie between UCF, Fairfield, FIU at 11-18.
If JMU pulls off the miracle in the downtrodden CAA, then they will be 13-20 and slightly better than those 3. Instant media darlings as the lovable losers.
1- US Hockey wins the 1980 gold medal. Not only did they beat the favorite Russian team in the semifinals, but they beat several other European teams that featured pros against the amateur US team. They tied Sweden in the first game and then won 6 straight
2 - NC State 1983 basketball champs. They were 17-10 after the regular season and had to win the ACC tourney to make the big dance which they did. Then they won 6 straight games for the NCAA title.
3 - not on the national radar, but East Carolina won the 1993 CAA tourney when it was only an 8 team league. They were 10-16 (4-10 CAA) and then won 3 straight games including over #2 ODU and #1 JMU in the finals.
