Too big, too physical, too quick. Wichita State proved to be too much of everything for La Salle in a 72-58 victory Thursday night that put the Shockers into the final eight of the NCAA tournament for the first time in 32 years. They overwhelmed the Explorers with a 14-2 run to open the game that had La Salle playing catch-up the rest of the way. The Explorers trailed by 22 points early in the second half and by 20 late.
