I believe in the press conference and on Finsiders. He will call the plays for at least the first year. he says he really enjoys it. If he finds the right person for the job he may hand it over. I guess the question is, since I am to lazy to look it up, is.. What are the offense stats\standings when the HC calls the plays.
Some say it is too much for an HC to take on the coaching duties plus game planning and calling plays. Guess we will see.
calling plays doesn't mean you don't need an OC
