Exactly. With the supporting cast this team doesn't need Barrett to make NFL caliber throws. If he can make the right decisions on read option and understand the intricacies of the passing and screen game, he doesn't need to be a world beater. Limit mistakes and turnovers on his end, let the speedsters make plays, and hopefully the defense is coming to play this year.
What made Tebow special wasn't that he could rip off 50 yard runs every game like Braxton or that he had a cannon for an arm. He could not really rip off big runs and we all know in hindsight his arm is pretty sub par. He just had a mastery of this offense.
