No they didn't, they paid pick 3 for pick 12 (15 after bids) and Baker and Owies.Eagles basically got Baker and Owies for pick 19ish. Wasn't that bad.
I'm assuming you landed on pick 19 using the DVI points to conclude that they only paid pick 19? They are useless for anything other than matching bids, they have never shown the true value of the earliest picks and this has been conceded by the AFL who have made changes for next year.
This is a disaster for a club so early it's rebuild. They're still at least 3 drafts away from being a finals team and by that point Baker will be in his 30s.
