The opening games of the NCAA tournament were not for the faint of heart or the fond of bracket, with four games decided in the final five seconds and one close finish coming on the heels of another.

As usual, the brackets bore the worst of it. How cataclysmic were the results? ESPN reported that a mere 93,119 of the 5.9 million brackets submitted are perfect at this point.

Temple, a No. 7 seed, upended No. 10 Penn State, 66-64 on a basket with less than a second left by Juan Fernandez. Moments before that, No. 13 Morehead State toppled No. 4 Louisville 62-61 on Demonte Harper’s three-pointer from the top of the circle with 4.2 seconds left. Earlier, No. 8 Butler beat No. 9 Old Dominion 60-58 on Matt Howard’s buzzer-beater.

And, just when you thought it was safe to relax, Kentucky beat Princeton 59-57 as Brandon Knight scored with — see a trend here? — two seconds left.
