If I were Morris (which I am not, for the record), I would respond with:
You know I gained 1613 yards, 13 TDs, 4.8 yard average back in 2012 with RG3 at QB and an OL of Trent Williams, Tyler Polumbus, Kory Lichtensteiger, and Adam Gettis, and a few other probably forgotten no-names. Followed it up with two more 1000+ yard seasons. I think I can do pretty well with Dak, and a really, really good OL. Got quite a bit of experience as a RB with the read option. And I am not going to do anything stupid and get suspended.
And, I ran well in the 1st preseason game. Albeit, against backup Cardinals. But, you didn't like what you saw?
This ain't my first rodeo partner. Quit worrying. We got this.
Sincerely,
