Right, and there have been several decent hybrid franchise ideas tossed around here that found ways to involve legends, whether it be releasing a certain amount into the draft for a few years or starting each legend off as a rookie and letting them progress the way they did in real life or throwing them in at their prime.
It doesn't have to be the center point of the game, but just an option...why alienate a decent size portion of your fanbase because others think it is silly? It would have no impact to those that don't want it and would satisfy those who do....Win-Win situation.
