"If you would have told me in October that this was going to happen I couldn't possibly believe it," La Salle coach John Giannini said of the losing skid. "Going into the year no one had an inkling this could possibly happen. They are not going to quit. I am not going to quit."
The Explorers got 10 points from forward Jerrell Wright and 11 rebounds from center Steve Zack, but it was not enough. Richmond made 5 of 6 treys in the second half.
"They just started hitting shots," said Duren, who added four assists. "They got a lot of the same shots in the first half."
On the other end, Giannini said Richmond made it difficult for La Salle to get good looks at the basket.
"They do a great job of switching on defense," Zack said.
Allen made a basket and free throw to extend the lead to 46-39 with 9 minutes, 10 seconds to go, and his basket made it 48-41 with 8:25 left.
"There are not many guys like that," Giannini said of Allen, a 6-foot-8 sophomore who made both of his three-point tries. "They are such hard matchups."
La Salle has to win its four remaining regular-season games to finish at .500 in the A-10.
