What is a "dual threat" QB in your eyes?

In discussions about the UGA/ND game, I've heard a lot of people call Riley Leonard a "dual-threat" QB.

But is he?

In my mind a dual threat QB is a QB who can both run and pass very well. If their ability in one area is only mediocre, they're not a dual threat guy in my eyes.

For example, Matt Stafford could run a bit, but he couldn't run well enough to be called a dual threat. John Elway on the other hand could move in college and even though he was primarily a passer I would say he was a dual threat because unlike Stafford, you did have to respect the run.

On the flip side Eric Crouch could run incredibly well... but he wasn't a great passer. He wasn't a dual threat, he was simply a running QB. But guys like Mike Vick and Cam Newton had both the throwing and passing ability to be considered dual threat, even if their running was perhaps a bit more electric.

I don't think Riley Leonard is a dual threat. He's a solid runner for a QB, having 750 yards on the ground this year. But he's a bad passer, with less than 2300 yards through the air. The only threat he has is his legs. He's not particularly efficient when he throws either. His highest career passer rating was 141 at Duke 2 years ago. He was at 138 this season.

He's low in terms of production passing the ball and on the low end of efficiency when the throws it.

Am I looking at this wrong?
