Jooey has zero worth to any club as he would be considered depth in any team intending to challenge for a flag, and far too old for any team a ways off to consider. The only viable options would be those mid range clubs (ie Tigers & Blues) who consistently overrate their list and their current ceilings/deficiencies, and even then you're looking at a 5th round + pick at the most as there's simply not requirement for them outside of being a GOP.
Speculation being that Armo has been enquired about, is young enough to be considered for a sizable contract and durable enough to be considered, in a bundle as a good to great player instead of a mediocre to good player like most players that get named would be initially rated has some worth, similar story to Jack who is younger and seemingly has greater scope to improve.
If for instance we're going to one of Melbs early picks, you can really only trade Jack out of the two to try and get it IMO, no one else on our list would really demand the pick.
