Why don't I see any future draft picks when proposing a trade?

Future draft picks may be traded in keeper leagues only. To change your league to a keeper league go to League » Settings » Edit Keeper Rules. The length of the draft is determined by your league's roster size and number of keepers set (e.g., if a league has 15 total roster spots and an owner selects all 15 as keepers, the system will show no draft picks for that owner–their roster is already full). In general, a team has [roster size] - [number of selected keepers] draft picks.
