I have to say that in my opinion this is a very well thought out and balanced theme. When I first saw the groups, there were some that I looked at and thought "there's no way a competitive $120M team can be made from those", especially given some of the exclusive players in other groups. But, just for fun (and in case it is eventually deemed desirable for owners to take a second team), I decided to choose a few of those NL teams that I thought were impractical, and for each of the three I tried so far I was able to make a team that I believe would be successful in this league.
Kudos to dvorr80 for this unique and fun idea. I hope the league fills because it certainly deserves to fill.
