"Guarantano just set the all-time SPARQ rating at the quarterback position.
If SPARQ is an unfamiliar term, Nike created it in 2004 to measure the overall athletic ability of elite athletes. The word is an acronym for Speed, Power, Agility, Reaction and Quickness.
Needless to say, Guarantano very well could be the most gifted athlete to ever suit up for Tennessee at the quarterback position."
Take it up with FoxSports and a bunch of other sites that reported it. So worst case he was second best ever in athletic ability.
