I think it would make the game better but it would also shrink the customer base. Say you've been in a world for 20 seasons. For whatever reason, we'll assume legitimate, you miss the pre-season. Already depleted, you lose a couple of starters to injury. You win 52 games despite doing the best you can with what you've got.
Now, in a MWR world like mine, tough ****. I don't want to hear your excuses. You know that coming in. But everyone in HBD doesn't want to play that way. Hence, the shrinking customer base.
