Opposing DCs have identified a weakness and are attacking it mercilessly. Pressure on our poor line means pressure on Lamar. He's been superman for half a season until the OL injuries piled up too high and defences exploited it. I have no doubt this will be fixed by a combination of Lamar getting better from experience with this type of pressure and better OL play.
And it’s hard to fix a weakness like that when you’re so undermanned because it requires more than just Lamar to get it right - the OL has to make the right reads vs blitz looks, the back has to pick up the right guy too, the receivers have to identify and adjust their route the right way - and Lamar has to identify and execute too
but we’ve seen that even when Lamar gets it right something else goes wrong like the OL sliding the wrong way and leaving more than 1 guy unblocked or letting guys jump and put hands in the passing lanes, we’ve seen receivers not ready to receive the ball on hot routes or just dropping the ball and yes we’ve also seen Lamar miss or hold onto the ball too long
but it’s more than just simply a “Lamar” problem
