From high major coaches on the west coast to a handful of ACC schools, the 6-foot-7 combo forward is drawing the eye of college programs and is a hot name on the recruiting trail.
"We are very happy with him," Bishop Gorman coach Grant Rice said. "He's going to a have a great career here. There's going to be a lot of big time schools after him, and they already are. So we are excited about Roscoe."
As a freshman, Allen was confined to the Junior Varsity squad. This year, he's playing Varsity, but because of the experienced returnees his role consists of coming off the bench.
"We have so many guys on our team," Rice told Scout.com. "For most normal teams he'd start. But he's coming off the bench for us and he's doing a really good job."
"He's fundamental on the offensive end," he added. "He can shoot the ball. He shoots it really well and is a great shooter. But he's also starting to attack the basket too and because he's so long he dunks easily."
During fall camps Allen, a 6-foot-7 forward, began to build his reputation. But Rice cites the Beach Ball Classic as his talented prospects coming out party.
"He had a big game," he said. "In the first round of the Beach Ball Classic against Bishop O'Connell he had 18 points and played really well. There were a few ACC schools there that saw him and followed up on him."
Allen's offer list already includes some west coast heavyweights. Arizona, Arizona State, USC, UNLV, Santa Clara and BYU have all put up offers. Virginia, Virginia Tech and "all of the PAC-10 schools" are showing interest as well.
Thus far Allen has unofficially visited a pair of schools. He's spent some time on UNLV's campus because of their proximity and he's also been to USC for an unofficial visit.
"He's a sure fire high major kid," Rice proclaimed. He's really going to be able to pick his school when it's said and done."
