Trade 21,22 Zero chance, not in a strong draft
Those picks will be late 20's by the time we get to select players with them. If you could get f1 picks for them it would be worth considering but Richmond, like other clubs, would need to weight the expected value of the future pick against the players still available. Part of the value of any f1 pick might also come from its potential trade value as well, which could really escalate if the counter party did a Collingwood.
I just don't think the club would or should have a pre-conceived certain idea of what it will do with those picks.
