Clark was already signed by the Ratbirds... David Paulson will get the TE-route packages but DJ (David Johnson) will be the #1 for blocking priorities. If you are asking because of FF, then I wouldn't draft either guy. Miller shouldn't be out for more than 2 games. It's more worth drafting Miller in later rounds because a lot of people think he is going to miss an extended period of time, which he is not.
I took Jordan Cameron in the 11th and got Miller in the 14th. I feel really good about those moves!
