The pristine season, the presumed NCAA championship, the aura of invincibility and every other plaudit being thrown at the so-good-they’re-scary Wildcats are all at great risk. The Fighting Irish, with a long history of slaying basketball behemoths, stand in Kentucky’s path to the Final Four and perhaps the first undefeated season in the college game since Bobby Knight’s Indiana squad ran the table 39 years ago. On Saturday night, Notre Dame gets another chance at bringing down this team of teams, one some think is invincible — you know, like the 1974 UCLA Bruins, who had their 88-game winning streak stopped by ND. Kentucky has a half-dozen future NBA first-round draft picks, and the top-seeded Wildcats (37-0) are coming off a 39-point win over West Virginia in the semifinals of the NCAA Tournament’s Midwest Regional. Kentucky showcased all of its splendor — size, depth, defense — in running the Mountaineers out of Quicken Loans Arena. [...] beyond having one of the most efficient offenses in the country, three-point shooters and underrated toughness, the Fighting Irish believe. Something that I and this team have preached on the whole year is that we’ve kind of been writing our own history, doing things the Notre Dame basketball program hasn’t done in a long time — or ever. Kentucky doesn’t beat itself, but head coach John Calipari disagrees that someone will have to play a nearly perfect game to upend the Wildcats. Kentucky’s Andrew Harrison said his dislocated left ringer finger was sore, but the Wildcats’ leading scorer doesn’t expect it to slow him Saturday. Harrsion got hurt while trying to make a steal in the second half against West Virginia, and his finger was bent so grotesquely that a Kentucky trainer ran on the floor and threw a towel over it. Harrison headed toward the locker room, but quickly returned after the medical staff popped his finger back into place. When he returned to the bench, Calipari wanted to know if it would affect his shooting touch. Notre Dame went 14-4 in the ACC, quite a turnaround for a team that won six conference games last season. Not only did the Irish acquit themselves during the regular season, but they then went to Tobacco Road and beat Duke and North Carolina in Greensboro on consecutive days to win the ACC tournament.
