Letting players go for nothing in spite sounds like an excellent list management strategy. Lol.
He's worth a mid to high second rounder. Why you'd prefer you get nothing for him is both baffling and amusing.
A mid to high second rounder is worth a lot less to GCS than it is to other clubs, they may not even need it this year. They can't just let clubs waltz in with rubbish offers for very high draft picks, that is more damaging than losing a player who contributes very little on the field and a draft pick they don't need.
