I am surprised that so many of you are embracing the "ugly game" or "ugly win" narrative about this game. The only ugly thing about this game (from UConn's standpoint) was the shooting percentage (overall and on 3's). It's an example of basketball's oldest fallacy -- that shooting well = playing well, and the corollary that shooting poorly = playing poorly. It ain't true, and Geno takes every opportunity to point that out.
Among the non-ugly aspects of the game for UConn were the low turnovers (just 10 for the game), the 20 assists on 27 made field goals, and the 30 points in the paint (considering that Seton Hall only scored 34 points overall, and only 10 in the paint). Also, the 45 rebounds including 14 offensive rebounds aren't too shabby either. Nor were the 18 fast-break points (compared to 2 for Seton Hall).
So the "ugliness" comes down to shots not falling. For the most part, the shots weren't bad ones -- they just didn't go in. You have to count on the law of averages to fix that over the course of a game, as it eventually did -- UConn shot 16-for-30 (53%) in the second half.
Some of you mentioned fouls, and KK in particular was conforming to the "dumb freshman" stereotype in that respect. But even so, 15 total fouls for the game is not an unusually high number, and no one other than KK had more than 3 fouls.
