Actually Baltimore is a bad landing spot historically because they have drafted a ton of busts at the WR position over the last 2 decades. They haven't had a WR develop into a top or even near the top of their depth chart since they were the Browns. Torry Smith perhaps the most successful of WR they have drafted. Or maybe Stokley but he didn't do anything until he played with Manning.

So it isn't just about Lamar Jackson, at least in my view.
Incidentally I was watching Lamar Jacksons throws from last season and he can throw a very accurate ball. He doesn't do it consistently yet. How little the Ravens allowed him to throw the ball is more of a concern to me than his ability to do it.
