There's a difference between "relying on your legs" and "using your legs to extend plays". He's doing the same thing Aaron Rodgers does, he's just more athletically gifted, although they do script some specific run plays for him. But he's still not a "running QB" and I would imagine as his NFL career continues, he'll be running less rather than more.
(Especially if he's destroyed his ACL)
You just don't throw for his completion % (65.6) or his ypa (8.14) if you're just a runner at QB. Much less his 20/5 TD/INT ratio.
