Ewing Theory doesn't really apply to football in my opinion. Football isn't a sport where a star player can be detriment to a team as no one player consumes the ball or the action like you see in other sports. The only position I can really see it be applicable is QB. I suppose I can envision a scenario where perhaps you always had a lousy team but then some exciting mobile QB came along and made the team better. But as the team develops and gets better talent, the exciting QB becomes a detriment as he doesn't distribute the ball to your playmakers as much as he should.

The NFL does a good enough job running off guys who aren't talented or who have lost their talent with age/injury. If ARob became a detriment because he was taking reps away from better WRs on the bench, ARob wouldnt see the field because the better WRs would already be playing.
