Yep, they had that set of seats on the floor that was nicknamed "Gucci Row," because you had to be rich enough to buy Gucci to also afford those tickets.
OU has only played UNLV twice in Norman in men's basketball. The first was still the greatest game I've seen in person (1987 game, which OU won, 89-88, and was played in front of a huge crowd despite a foot of snow being on the ground outside). The second was in '90, when they ended up winning the title but were missing a couple of guys who were strong rebounders (ineligibility).
The OU media guide, after Dave Bliss left, incorrectly listed the '77 game as being in Norman. It was in a tournament out there, and a Final Four-bound UNLV team beat our kiddie corps by a score of 100-89. It was a five-point game in the last two minutes, so that was no blowout. That was the OU team that started two freshmen, two sophomores and a senior (and had no juniors). I think then-frosh Aaron Curry had about 28 points in that game.
