It happened again last night when Kentucky, which like Maryland had some embarrassing non-conference losses early in the season, beat No. 3 Tennessee, 72-66, in an SEC game. And as was the case when the Terps toppled the Tar Heels, defense was the key for the Wildcats, who were 7-9 overall going into the game. Tennessee (16-2) was held to less than 39 percent shooting from the field and 20 points under its average. Meanwhile, although Kentucky got off 12 fewer shots, the Wildcats made nearly 49 percent and were steady at the foul line, making 24 of 28.
