Sorry it was a question and I am still not sure of the answer. Not sure if I am being clear.
Does the role a player has change his development? For instance does playing inside linebacker vs outside linebacker or DE vs DT change the way a player develops if everything else is the same or is that all determined by practice plans?
As an example the default rolls indicate that strength and tackle are more important for DT than athletics and speed. If I play a player at DT will his strength and tackle improve faster than if I played the same player at DE?
