I appreciate the optimism, but living in Colorado I saw enough of Simien to know a week of practice as the starter won't fix him. He's not a starting QB in this league. It would be a miracle if he suddenly transforms into a starting qb with any semblance of consistency.
How many thought Jameis was a lost cause? Sean Payton has the knack of identifying diamonds in the rough. I would bet that Trevor is not the same QB now that he was two and three years ago.
