Two problems: You can't keep all said players and then include players that came from trades after they left, etc. Like another poster said, Zimmerman would have never been drafted by the club. This is *not* the team that we'd have had if not for MLB and the GM. This is a "what if we could have the best players from the past six years" team. Any other ball club could do the same thing this fellow did and they would have equally impressive rosters.
Second, what on earth is the payroll for this team? Great, we "could" have had said team. Good luck finding a club to have all those players on the payroll at the same time...
