Taysom probably has a stronger arm. But Jackson has demonstrated pretty good accuracy and touch. We have no idea what Taysom could do as a passer other than hurl the ball downfield on pretty simple plays. But there is no denying that his ability to run and his arm strength opens up the offense. If you took away Lamar Jackson's running ability, I'm still not convinced that he's an NFL QB...but like Taysom, you can't discard his running ability and how much it opens up the rest of his game.
