The year they beat Princeton was when Wes was on the freshman team, so he didn't play in that game. The next year, when the team had Wes, Toby, Dan Hesford, Tom Penders, Ron Ritter and company, the team went 23-2 aduring the regular season and I'm pretty sure the 2 losses were in a row with Wes and Toby both injured for one of the games and the other one (don't recall which) not back to the other. One of the losses was to the despised Holy Cross whom we stomped in the other game - we played them twice a year back then. The year they beat Princeton, where Dom Perno stole the ball from Bradley to seal the game, the team was good but not great. They showed the game on a big screen at Jorgensen - TV was a big treat back then, and the students estimated at 1-2 thou, went nuts afterwards, marching on President Babbidge's house (best Pres UConn ever had) who handled the crowd great. UConn went on to play - hate to say it - Duke, in the Regionals and got crushed by 50 or so.
The next year, with Wes and Toby, the team got a crap draw in the NCAA's having to play the higher ranked St. Joe's on their home court at the Palestra in round one. They lost. St. Joe's was led by guard Matt Goukas who was unusual for a guard then at 6'6" and talented. Wes had a hard time shooting over him. In that game, Kimball set a crazy rebounding record (maybe still stands?) for an NCAA tournament, at something like 29. One of the Philly paper headlines the next day was about Kimball even though the Huskies lost.
A little more history. I can't remember if it was Wes' junior or senior year. The NIT then was almost as big as the NCAA, especially with the small NCAA field and only one bid per league, the team being the regular season champ, or for the few leagues then,. like the ACC, that held a post season league tournament, the tourney champ. The Yankee Conference was not a league with an automatic bid. So UConn that particular year, didn't get invited but was invited to the NIT. UConn turned down the bid and the interested students pretty much rioted. The explanation by the old AD, J.O. Christian, was that UConn owed its allegiance to the NCAA (ironic, isn't it), and was not swayed when it was pointed out to him that the NCAA was snubbing UConn (some things don't change) and that every team in the NIT field were NCAA members.
