1987: Mugsy's senior year, WF was horrible. He was great, but the rest of the team except for Mark Cline was super-young.
WF finished 2-12 in the ACC; WF's two regular season wins were over 0-14 MD, who essentially played all walk-ons and frosh after Bob Wade had committed a series of NCAA violations. Clemson finished 2nd in the ACC that year (10-4, and they were loaded: Horace Grant and Elden Campbell were as good an inside tandem as any team in the country). WF pulled a shocking upset Clemson in the ACC Tournament quarters, and faced #6 seed NC State in the semifinals.
The Pack had had a disappointing season. They were ranked to start the year, but stumbled in ACC play. Even so, State was a loaded team, Valvano could always recruit, and they had 4 future NBA players: Vinnie Del Negro, Chucky Brown, Charles Shackelford and Brian Howard; their leading scorer was Bennie Bolton. State had upset #14 Duke (Tommy Amaker, Quin Snyder, Danny Ferry) in the quarters, and WF played State in semis. Valvano and Staak were buddies, Valvano had recommended Staak for the WF job, but Valvano owned Staak head to head, including some incredibly excruciating losses. While it was fun that WF upset Clemson, everyone expected State to roll in the semifinals, as WF had only beaten depleted Maryland in the ACC regular season.
Behind an epic performance by Mugsy, WF led late in the game, and IIRC, WF should have won in regulation (perhaps, a controversial call by Lenny Wertz?), but the game went double OT, and State won.
UNC (loaded beyond belief with 7 future NBA players including Kenny Smith and JR Reid) had ripped through the ACC unbeaten 14-0, and were ranked #1 or #2 all year (fwiw, Jim Boehiem's Syracuse team, led by Derek Coleman, upset UNC to win the East regional, and Cuse lost the NCAA title to Bob Knight's Hoosiers on a last second shot by Keith Smart). UNC played NC State in the ACC tourney finals, and everyone expected State to lose big as UNC had routed the Pack in both of their regular season games. In true Valvano fashion, State upset UNC in the ACC final to win the conference title. The ACC had 8 teams that year, and only WF and MD failed to make the tournament. Think about how different that is than the ACC today.
