He's a winner thus far, but no matter how much he keeps winning, he will be fighting the ghost of the second string quarterback.
What he's doing is creating another "Flutie-Mania" kinda thing. I love the kid because he's a former Gator, but I feel sorry for him because if he keeps up like this, he'll still be proving himself all the way until he retires.
In all seriousness, though, as much as I love the guy, he's GOT to work on throwing the ball..you know...only the most basic fundamental skill of a quarterback. Then again, another quarterback in Denver started out like this, and only became a good pocket passer (and two time Super Bowl champion) later in his career. The difference being, however, that Elway ALWAYS had a gun. I think he scrambled around a lot because he wasn't sure what to do with the ball, and well, he COULD scramble. Later in his career, he no longer COULD.
