Carmichael has to call more quick timing pass plays to help out his QB. Get the ball to AK in space as much as possible when he’s alone in the flats. Utilize the short-intermediate passing game to the TEs, RB, Thomas and Olave, instead of forcing the QB to wait for deeper routes to develop on majority of plays.
Keeping whoever’s the starting QB clean from unnecessary hits with better protection starts with the OC’s playcalling. It really shouldn’t be that hard to implement the quick passing gameplan again if they want to keep the QBs healthy.
