It really won't. I've not said anything about Gorappolo that is going to be proved or disproved. What I've said is that right now he has ten starts, two of which he didn't finish, so there's really no way to assess whether he is average, good, great...or completely out of his depth. At the end of this season, if he has 26 starts we might be in a position to evaluate his merits. Our disagreement is that I'm not willing to say things like "as long as Jimmy G is in there SF's offense will be great," because unless the guy is an absolute rock solid superstar SF's offense is going to be an adequate at best group of personnel undergoing adaptation pains, and nothing to turn the franchise around overnight. Saying right now that he is that kind of star is pure speculation. It may turn out that he is, but that doesn't make saying it now anything more than a shot in the dark.
Just like I can say "Nick Foles is gonna be the biggest deal to hit J'ville since...well, ever." It may turn out that a year from now that is totally what happened...but that won't change that saying it right now is pure speculation shot in the darkism.
