Other than a game here or there seems to me Offense hasn’t been in sync since the Bye last year. I would revolve the offense primarily around Cook and to a lesser extent Kincaid. Running the ball, screens, swing passes, and splitting him out wide to get him open in space. He is our best player in terms of yards after the catch potential.
Knox should be the primary blocking TE and check down option while Kincaid is your intermediate threat. Not sure what is going on with Diggs but getting Cook and Kincaid more involved in the passing offense should help out the WRs.
