Knoll says it's a great idea for those who can, to mix athletics with charity.

Knoll has the unique distinction of having served his country in four separate conflicts.
He joined the Marines in 1950 and served in Korea and Vietnam and then served in defense intelligence in Afghanistan and Iraq, ending his military career in 2003.
