Why does it have to take place in a one week off-season?
The whole idea is it is a process that takes about a week, executed when the GM is ready to go looking for a player. I just joined, and I think that most of the owners in my league are new like me. If a bunch don't bother with their draft list, then I may be able to get 3 5's. Or someone might join up a week after the draft and miss out completely.
Participation can be fairly inactive. Someone wants to go FA hunting, so they click on a button and are assigned to a scouting combine that starts on say Sunday, where they can see the players in the scouting combine, which would constitute names, height, age, and position. The first game would be played on Sunday and could be watched live or in replay. By Monday, GMs can ask for one player skill to be revealed. All GMs will be able to see this information. If a GM doesn't select a skill, it is just a little bit less information that is available.
The second game would be played on Tuesday, with another skill revealed on Wednessday. The third game would be played on Thursday with the 3rd skill revealed on Friday. GMs have until Saturday to order their top 5 picks, and they will know on Sunday who they acquired.
But let's expand this a little bit. Let's recycle all players. If a team is about to be replaced, dump all of its players in the FA pool. Any players that are fired also end up there.
The pool would have a fairly large depth (perhaps a minimum of 5 x the number of active teams), so that players who go in the FA pool don't recycle immediately. If the pool becomes too shallow, then new players will be generated.
New teams are given 12 players from the FA pool, and 6 combine credits, which will let them acquire other players of their choosing if they like. Existing teams will get 3 combine credits each season.
The combine players are selected from the FA pool, 20 players for 12 teams. The players that aren't selected from the combine are dumped back into the FA pool. A record would be kept of players rejected 3 times, who would be removed from the FA pool. Since a player has about 8/20 chances of being rejected, about 6.4% of players would be removed each season.
Perhaps a GM could participate in 2 or 3 combines at a time. If an existing team wanted to do their player acquisition at the end of the season they could do it in a week. Or they might spread it out over the season. New teams could take their time getting used to the game, and then start looking for some new players.
