This is the issue with Baltimore and Lamar Jackson. When they get into a big game where they are trailing, their run game and Lamar's running abilities become useless because it becomes obvious passing situations, and then Lamar usually can't pass the team to victory like Mahomes/Allen/Burrow can.
And so far, Buffalo is stacking the line, and then blitzing on obvious passing situations. Romo is highlighting this too. And Lamar meanwhile has been a puddle, with that bad fumble, taking a horrible sack near the endzone, and missing a few guys too. Baltimore hasn't done much since their first drive.
