Sure- a local named Doug Shanahan played both at Hofstra. He was the first Tewaaraton winner. He ended up in the Jets camp, left, now back in the MLL. Will Yeatman, a kid at Brown recently, im sure there's some at the military academies, etc. Even Eric Hatkewitz did 2 years at safety for SB. But back in the day, this was WAY more common.
But literally every kid coming to SB Lacrosse (check the recruiting threads or the alumni site) has a fantastic football background. Just thought that was worth mentioning.
