Spencer Rattler’s first start was…

We have an idea that he has the talent and that the game isn't too big for him. And there is no guarantee that Carr makes any of those plays either. On the other hand Rattler did some things that Carr can't do and it's time to get him the experience to find out if he can learn to do those things and continue to do the things Carr can't do.
Carr can do roll-outs with single and two-stacked reads. He's done many this season. I'm not sure why you guys are suggesting he can't.

Rattler wasn't out there scrambling like crazy and making guys miss. He had a few good scrambles up the middle for relatively short gains, but I did not see a guy who is going to win games with his athleticism. He's going to need to develop into a passer who can take advantage of his big arm.
