Asked about his range, Rosen quipped, "The building," and laughed.
Turning serious, he added, "I don't know. I practice it, and I work at it. Coach trusts me, and luckily tonight they went in."
Allen, however, did not want the game to get to that point. Cornell's offensive rebounding was a problem, taking the Big Red from a seven-point deficit to a six-point lead in the second half. The visitors shot 48 percent in the final 20 minutes and kept it close to the end even though the Quakers shot 50 percent in the game and 54.5 percent from three.
"As much as I like [Rosen], I don't want to rely on his heroics to win basketball games," he said. "I know he's capable of making tough shots. I'm not saying the game shouldn't be that close, but we just put ourselves in a position where we've got work extremely hard to get the results that we want."
The Big Red (10-13, 5-4) took control with a 19-6 run through a 51/2-minute stretch of the second half, including a five-point possession after Penn sophomore Cameron Gunter was called for a flagrant foul for landing an elbow above the shoulders of Cornell's Shonn Miller. Johnathan Gray hit two free throws and Eitan Chemerinski converted a three-point play.
Down by six, 49-43, the Quakers answered with a 9-0 run with Rosen contributing two short jumpers and an assist on a three-ball with 8:56 left by Tyler Bernardini, who did not start because of a foot injury but gutted out 22 minutes.
Cornell put together a 7-0 spurt a short time later to regain the lead at 59-55. That's when Rosen went to work.
He hit a deep three and two free throws to give Penn a brief lead. After Chris Wroblewski drained a three-ball for the Big Red, Rosen cranked one in from Franklin Field to put the Quakers in front for good with 2:48 to play.
"I couldn't believe he took that shot," Cornell coach Bill Courtney said. "That was unbelievable. How do you defend that? Some of the plays he made tonight were terrific."
The Quakers got two defensive stops and Rosen drilled yet another trey. Wroblewski's two free throws got the Big Red to within two with 1:04 left, but Rosen broke out of a double team as the shot clock ticked down and found Cartwright in the right corner for the decisive three-ball.
