Jennings has a big arm. With the flick of his wrist the ball goes 40-50 yards. Has shown some good accuracy as well (both from the pocket and rolling out). Anybody trying to argue against his potential as a QB is absolutely ignorant. And his athleticism is readily apparent as well. Maybe doesn't have the wheels that TG has, but JJ can play QB.
As for the TN vs FL talent argument, FL has a lot more talent than TN. Nobody is trying to deny that. However, Tennessee does have a good amount of talent, and a disproportionate amount of that talent was on display in this game today. So, while overall Tennessee has less talent, that doesn't mean that our best teams would get smoked against all of Florida's best teams.
