There were doubts that Lamar could improve his accuracy since his college numbers were not that strong. The fact is that he worked extremely hard in the off season to improve his passing and he seems to have improved. I think Jackson's biggest issue going forward is his lack of protection from his O line. The last couple of weeks he has been under duress from the pass rush. Further, Cleveland and Pittsburgh have contained him well when his protection breaks down. It's understandable, but it seems his throwing mechanics break down under consistent pressure.Overall, he has improved as a passer and the overall numbers bear it out.
But I wonder how much of that is Lamar just holding on to the ball too long and not going through his progression of reads quickly enough? Or are the receivers not getting separation or running their routes properly? It could be a combination of a lot of things in addition to poor pass protection. What I do think Lamar is not doing this year compared to 2018, is he's not making a decisive move as quickly to get out of the pocket and run downfield. He looks a lot more determined this year to stay put and get the pass off and if he takes some sacks, so be it.
