Here is what I propose.
With 3 keepers, people may want to make some off season trades, and they usually work better if people can also move draft picks. I suggest this:
1) Trades have equal numbers of players and picks. If I trade a player for a #3 pick, I send back a player and a lower pick. (Like the last pick #16)
2) Trades are posted here in this forum for a week. Unless there is some formal protest consisting of several other coaches, they are processed by the commissioner. (I'll keep a list of teams players and draft order as trades happen.)
Does this sound good?
UPDATE: Measure passes. (NH can open his thread now...)
