The blueprint to "contain" Lamar Jackson is fairly straight forward but often too difficult. It starts with run defense up the middle and edge discipline to try and keep Lamar in the pocket. If the RBs gash the middle, it's gonna be a long day. If Lamar can get the edge it's gonna be a long day. He's so damn fast that you think they have a line on them but he still gets the edge and turns the corner for a big gain. The other part is to control their TEs in play action which is easier said than done because if the LBs are being sucked up to stop the run, the TEs will have more space. Therefore, the goal is to stop the run up the middle, control the edge, control the TEs, and force him to throw to the edge.
Baltimore panicked last night and felt they had to get into a shootout. If they would have stuck with what their strength is, they might have had a better chance.
