So was JaMarcus Russell, Ryan Leaf, Johnny Manziel, Todd Marinovich. Just because Tebow wasn't as big a bust as they were doesn't mean he wasn't a bust.
And as an NFL starter he had a winning record. An above average winning record in the NFL.
Eight and six over three years.
Are you saying about these players what you said about Tim Tebow: he was never an NFL caliber quarterback?
