just set if up so guys can keep players by giving up the round they picked them in. For example, say you drafted johnny Peralta in the 15th round last year. Maybe this year you get to keep him by giving up your 15th rounder. The only thing you have to decide is how many rounds it should be moved up each year. Do want to make it so the peralta owner gets to keep him at that price forever, or should it move up next year. Personally, if i was doing a league like this, id do it in the following manner.
The first year a player is kept, the owner gives up their draft pick the round they were chosen in.
after that, the draft picks moves up each year.
rounds 11---> whenever. The player moves up 4 rounds each year until they reach round 10. Example: you drafted felipe lopez in round 20. In year 2, he is a your 20th rounder, year 3 your 16th rounder, then 12th ect
rounds 1---->10. move up 2 spots each year. you'd have to decide what to do with 1st roundrs
This system is kinda confusing, but i think it would work well. Although owners should be rewarded for their good late sleepers, you dont want some guy living off a 20th round albert pujols for a decade.
