re: I called it- OU is unstoppable

Buddy is a nice player.
unstoppable seems a stretch.

You might have missed the Villanova upset win in the finals over Patrick Ewing.
Villanova had one player who was a decent forward in the NBA.
Ewing was Olympic, NBA all star.

Frigging Wilt Chamberlain Kansas lost to UNC by a point in OT in the finals. UNC's best player was waived out of the NBA in mid season.

Heck, Princeton (with NO future NBA players) nearly beat Georgetown (lost 50-49, had the ball and the last shot and missed), in one of Ewing's NCAA runs.

Lew Alcindor's UCLA also with Luscious Allen, were taken into OT by Drake in the semi's.

If the opponent has two or three players have real nice days, your famous great player loses. It usually takes more than one really good player to do it.
UNC Charlotte was an example of what you are hoping for. Cornbread Maxwell was enough by himself to beat a Michigan team with 3 future NBA guards, but Maxwell defeated the big lug playing center for Michigan.
Maxwell broke the press. the big lug never even tried to guard him out on the floor. so the brilliant Michigan press never could happen. Michigan had three perimeter players make it in the NBA. center washed out though.

Is that enough examples?
