I've done the Fox based one for Super Rugby for a few years, but tried the Fantasy Draft one (
www.fantasyrugbydraft.com) with a few guys on here last year.
I'll be doing the Draft one again this year, because I like the fact that you can't have the same players in your team, as the players in the teams you are competing against. The fact that your team (and everyone else's) is unique, means that you don't end up with near identical teams as the season progresses further.
The drawback is, that the game participants need to be active each week - last season, there was only about three or four of us, out of ten, that were active. This meant that there were only a few games that were competitive, and it was very frustrating trying to trade players, because you wouldn't get a response from the inactive guys.
Anyway, I'm hoping to get involved with ten active people this year - I believe it's 101 days away, as of today so hopefully I can renew the rivalry with Darwin and Gena ... something to think about for the rest of you, if you want to try something different, and you can commit some time
