Hogan probably was worth more last year - similar level of injury issues, but younger and wasn't a FA in 2019 so would have taken a trade regardless if he left. Daniher being a FA next year means that he can't be worth two top 10 picks.
I'm assuming purple is repeating what he's heard from Essendon rather than anything you guys are actually entertaining.
Plus Fremantle were so desperate and have been trying to get a key forward literally since the club was founded.
