I actually completely agree with this!
The NFL seems determined to expand to Europe...specifically Great Britain, and since the Brits are already familiar with the Jaguar cars, a Jaguar team makes sense.
Heck, it might even make marketing sense for the Jaguar car company to actually own the Jaguars Football Team.
The biggest problem, of course, is logistics of travel for all of the other NFL teams, and also what division the team would be assigned.
