Corley was indeed very good. Thin (think Jeremy Lamb) , but could jump out of the building and very athletic and a good shooter who, in those days at 6-7, mostly played around the hoop. He would fit in very well in today's game.
There is one thing about his 51 point game, however. I remember this pretty well. First of all, UNH was lousy, and I think only because of that could the record have been set in the way it was set. His coach, Burr Carlson then in his first of 2 or 3 memorable years as one of the school's least successful coaches, looked up at the clock with under 6 minutes left, and felt that Corley could beat the old record (50 points) that Wes Bialosuknia (my year) had set, mostly on long range bombs, the year earlier. The only thing was, Corley had 27 points at the time. He scored 24 points in the last several minutes, mostly being fed for lay-ups, in an era without a shot clock. Why Carlson thought such a thing was possible in such a short time with Corley at half the record only he could haves said (I guess he knew best) and only an opponent so inept could have been so accommodating.
But Bill was a very good player. He was from Long Island and the story at the time he chose UConn, probably true, was that he was from the same home town as Duke (sorry) superstar Art Heyman who had been recruited to Duke by former Duke asst. coach Fred Shabel who had gone on to become UConn's head coach -0ne of our best. Supposedly Shabel enlisted Heyman to convince Corley to pick UConn. Shabel's 4 years at UConn matched my own 4 years and he left to head the Spectrum in Philadelphia where the 76ers played. BTW, because he came out of Duke, Uconn often used Duke's signature 2 handed floor slap on D. But no flops, it was pre-Duke's flopping coach.
