Penn’s first game last night under interim coach Jerome Allen looked an awful lot like a bunch of games the Quakers played under the fired Glen Miller. The Quakers shot poorly, didn’t defend well at all, got crushed on the glass and were out of it from the start in their 79-50 loss at Davidson. Penn trailed 8-0 out of the gate and made just 2 of 11 3-pointers (18.2 percent) in the first half, during which time the Wildcats (5-8) were 8-for-14 (57.1 percent) from downtown. Game over. Davidson wound up making 13 of 30 from the arc on the night, and Zack Rosen was the lone Quaker to score in double figures. And guess what? It doesn’t get any better: On Thursday, Penn (0-8) plays at No. 7 Duke. Yikes.
