That depends on how long the duration is. If it's one year, then you would have chaos. I am thinking more like four or five years. Assuming a team can still hold a player for the first six years, then they can extend him another four or five years and there aren't a lot of players you really want to keep longer than that. A few superstars maybe, but players aren't staying with their same team throughout their career even the way it is now.
