So first suggestion is to not play Stubbie in run downs. Secondly, if playing Stubbie the safety needs to show up in the run game. we tell him to go make a play while the SAM sets the edge. I would also comment that the SAM is alllowing himself to be blocked by a WR….this should never happen. He needs to find the weight room…but seriously, the read is the read for the SAM. He just needs to get reps at it and be physical.
