Have any of those players suffered more than one injury? Because if so, I reckon your flogging a dead horse on here...
I like both Mills and Jones coming out of defence, I don't know much about Hall and Lonergan, but what happened to Liberatore? Is he not being offered a contract or is he a free-agent? Any indications he is looking for a change?
Liberatore has had the two knee reconstructions, which is unfortunate. He's a free agent, and the dogs have a few free agents they need to re-sign. There was talk in the media a little while ago that there might not be room in the team for Liberatore AND Wallis, so one of them may be available. I don't mind the idea of Wallace, but all things being equal Liberatore is the better player (as long as his knees are ok). It's a risk, but as long as he's cheap it's not a big one. Now that I realise he's a free agent I'm even more interested.
Lonergan is a midfield bull, wins contested possessions and has enough speed to break away / spread. His disposal hasn't been a strength of his career, but it's no worse than most on our list. He was a first rounder in 2012 (going back a fair way) who has consistently shown enough to keep his spot on the list but never really dominated like he was expected to. Would be very cheap, and might just need the change of scene to help him take the next step.
Hall is a bit of a strange one. He's an outside midfielder, blistering speed, great use by foot, kicks goals and sets them up. As an outside attacking midfielder he's pretty much everything you could want.
On the flipside there are BIG question marks over his accountability and defensive efforts. Sort of like an extreme Lewis Jetta, in that I would say he has more natural ability and weapons, but lacks Jettas defensive mindset (which is saying something). Again, a risk, but would be cheap and as an example of what he is capable of:
2017 round round 7, Gold Coast vs Geelong
In a match where Gold Coast beat a quality opponent, Halls stats read.
Good -
32 disposals at 75% (22 kicks, 10 handballs)
10 marks
8 tackles
1 goal 2 behinds
10 score involvements
569 meters gained
Bad -
3 intercept possessions
6 contested possessions
1 contested mark
19 pressure acts
3 clearances
1 one percenter
Which sort of sums him up as a player at GCFC. Elite outside and in attack, but not much for contests. That being said, it seems most GCFC supporters would be happy to see him go, and would be happy to take him in exchange for Newman.
