In the final minutes of a taut SEC semifinal, Kentucky’s Anthony Davis found himself defending Florida guard Erving Walker on the right wing beyond the three-point arc. Twice Walker rocked back and forth to wobble the 6-foot-10 Davis, whose outstretched right hand hovered high above the 5-8 guard’s head. Davis finally swayed too far right, Walker darted past, and almost everyone in New Orleans Arena could see that nothing stood between Walker and the basket.
