Well not exactly, because their are players that will come out of the draft that are much more developed in their skill sets so it should only take a "star" rookie LB maybe 2 or 3 seasons to make into a Ray Lewis caliber player depending on how much xp you use on that particular player, whereas you could pump several seasons worth of xp into a bum LB and eventually turn him into what that star rookie was just coming out of the draft. Lots of interesting variables here.
