Can still request a trade
Once you nominate a club publicly as a player you're locked in to that club.
Probably doing himself a disservice in the off chance another club (eg Collingwood) want to come in late with an increased offer, because if he's nominated he shuts them out. Also at this early stage, maybe puts too much pressure on the clubs involved.
Trade week is still ages away, and no one has nominated publicly yet, despite reports Tomlinson & Langdon have chose Melbourne, Hill has chosen Saints & Martin Carlton.
