I know, it's a mystery to me too. You don't want to take Lamar's street ball instincts away from him because so many big plays have come from it but if they expect him to operate within the framework of convention, maybe they should take a few pages out of the Steelers playbook and get him to release the ball a lot sooner. Pass protection is probably going to be an issue all year, just like it's been since Jackson took over at quarterback. Obviously, you need some time for longer passes to develop but for the most part, he's not going deep so just get rid of the ball before getting hit. That's all we need is for our best player to join the list of the IR fraternity.
No mystery to me. The Ravens RBs muffed at least 2 run options this game (that's what I saw, it could have been more.) I don't think Roman trusted his RBs to be able to correctly receive the handoff or let it go given that Williams didn't really have first-team reps until this week, and they signed Murray off the street and he barely practiced with the team.
Lamar normally waits till the last possible second to decide whether to give the ball or pull it back and I think he needs to be in sync with his RBs for that to work.
edit to add: The Ravens have never really featured much screening because defenses haven't really been overcommitting on the QB like they do for other teams. It's kind of hard to screen behind a mush rush.
