I don't know if sth. like this is already existing/planned, but I have the idea of a game, which would last over the whole 2006 season.
Everybody may choose 10 players out of the Top100 of the final Champions Race 2005. To prevent that everybody takes players 1-10 of the ranking, there is a rule that you are allowed to take only one player from 1-10, only one from 11-20, only one from 21-30,..., only one from 91-100. And: You are not allowed to take another player with ranking postions 11, 21, 31, 41, 51, 61, 71, 81, 91 if you decide to choose player number 1 Federer. So the last cypher of every number is only allowed to be chosen once.
So, one possible team could be players who are ranked:
6, 14, 27, 40, 41, 55, 68, 79, 82, 93
But as you can read, it's called Best of 20, so 10 players are still missing, you could choose those 10 players from all players who are not listed in the top100, anyone is allowed.
Of course the Champions Race on http://www.atptour.com
is relevant ( http://www.atptennis.com/en/players/championsrace/
The aim would be gaining as many points as possible in the 2006 season with the chosen players.
Hope, everybody understands how it is supposed to work, the only thing necessary would be enough participants
