IMO, in coming seasons Williams will be the strong side DE, and McDonald would the the weak side DE. Parsons will move around and rotate in when they want to use him.
Lawrence will be moving on soon, and Williams is plenty strong enough to play that spot. McDonald is on a whole different level than Armstrong or anyone else that would play on the weak side.
In the meantime, McDonald would work into the rotation and you’d be able to mix and match with DLaw, McD, Williams, Micah, Armstrong and Fowler.
McD would be one hell of a pick.
And yeah… he might be gone before 26.
