That was an awful game for UK, but it's not inexplicable that SC Jr swept UK that year. That South Carolina team had 3 excellent guards that gave UK fits, much the same way that Arizona did in the Title Game, and they finished conference play at 15-1. Also helped SC (a lot) that both games came after Derek Anderson went out for the year.
The type of 3 guard lineup that SC trotted out that year, where those guards were responsible for almost all the offense, was pretty uncommon in 97, but started to become very normal not long after. It's the reason that when Pitino came back to the college game, his UL teams never used the fullcourt press as intensely, or played at anywhere near as fast a pace, as his UK teams did. Too many teams were suddenly being built like those SC and Arizona teams, able to carve up a press and beat traps for layups.
