Seems the bolded is incorrect:There's no bidding on rookies.
If you nominate a F/S pick, that club has to take them at a minimum with your last pick in the national draft (like what we saw with Daicos)
Jarman wasn't nominated so both Adelaide/Hawthorn felt they could probably get him in the rookie draft. If someone gets in first then its Ade/Hawks bad luck. Any academy kids that were nominated and not bid on in the national draft are 100% up for grabs as well.
