Kansas City Chiefs offensive coordinator Matt Nagy was once a prized quarterback prospect before getting into coaching in the NFL. A University of Delaware product, he went undrafted after the 2001 annual selection meeting but found a niche for himself playing professional football in the Arena Football League through the 2000s.
His arm talent finally warranted a spot on an NFL roster in 2009, when he was briefly under contract with the Philadelphia Eagles. Outside of his AFL experience, though, Nagy has been known for his coaching ability, not as a star player.
