The 28-year-old told reporters: "It's definitely been an adjustment. I've kind of been through the process before. I kind of have a routine down that helps me. One of the biggest problems of learning a new offense is forgetting your past offense.
"Sitting down with guys talking to them about the game, the protection schemes, routes, how they have been doing it and what adjustments they are making. They really have made it easy on me, this is my job. This is what I do.
"I have been spending a lot of time in the playbook. I feel like every day I have been getting more and more familiar and comfortable with what I am doing. It was good to get out there today and put that on the field, communication wise."
