Well Lamar also runs an awful lot on non-designed runs. So if Lamar doesn't like running, his actions certainly haven't shown that.
I'm completely fine if we move on from Roman after another bad year. I'm just heavily pumping the brakes that if we bring in a more pass-happy coordinator (which lets face it, that's what you're advocating for), that Lamar will actually excel. I think we all need to accept that fact that part of what makes Lamar Lamar is that he can run the ball so effectively, and defenses have to account for that. If we start doing a lot less of designed runs, and start limiting his ability to scramble when he wants, then honestly, I'm not particularly interested in paying him $50M.
$50M pocket passing Lamar Jackson doesn't entice me in the slightest.
