Some point to Tannehill as an example of a jump like that. He was older, had better success earlier in his career before Gase, and was battling injuries, so some argue its not a fair comparison.
We really don't know what we have. You see flashes of a really good QB, there was just so much crap, it's hard to say.
We'll find out.
I don’t think our staff is going to look at QBR. You can have a great QBR and still lose games. Teddy ranking 17 is middle if the pack, yet he was 0-8 in game winning drives. If Darnold is 19, but makes the throws needed to win games that would be a nice upgrade. If he becomes the leader of the offense and gets some wins due to his play, I think we roll with him again.
