Defenses are setting the edges and he can't get outside. They are daring him to win with his arm, and he isn't much of a threat this year in that regard (a few heroic completions by Andrews aside). The Ravens are feasting on terrible teams, and they are lucky the AFC in general is pretty bad this year. Really the whole league looks pretty shaky. But the Ravens will struggle against any team that can score 20-30 every game. I see them as one and done in the playoffs unless they catch fire, which seems to happen with Lamar so who knows.
