Yeah the quality of the Giants' list hasn't really been realised by the public yet.I don't think they'll win a flag in 2016, but I think they could have a really stunning rise up the ladder next year if they have a real good run with injuries.
Smith, Treloar, Greene, Kennedy, Cameron, Shiel, Bugg, Hampton, Tomlinson, Coniglio, and Mohr are all in that 40-60 game range where players start to really mature and can consistently do all the things that senior level footballers do.
They now have a core of genuinely good veterans in Griffen, Patfull, Mumford and Shaw. You could probably add Ward and Davis to that list as well.
Scully, Palmer, Hoskin-Elliot, Whitfield and Haynes round out what I believe is a genuinely good first 22.
The problem is that every time one of the above players misses a game, they have to be replaced with a kid with <30 games. So their best possible season largely depends on how many injuries they pick up. If Mumford does his knee again I don't know how they'd cover him.
Mumford, Shiel, Treloar, Smith, Hoskin-Elliot, Ward, Griffen, Kelly and Whitfield is a group of midfielders and half forwards with the potential to be very, very good quite soon.
Shaw, Patfull and Davis give them experience in defence and Adam Kennedy will be a good 10 year defender. Obviously key forwards are a strength of theirs.
I think you're underselling their depth though. Below is my rough starting 18 for them in 2015. Coniglio, Greene, Lamb, Hampton, Buntine, Scully, Palmer, Haynes and Sumner are fringe or depth players. I see that as reasonable depth now, but in a couple years it will be greatly improved. Tomlinson, Plowman, Corr, McCarthy, Stewart and Mohr are fringe talls. Their three top 10 picks from this year's draft could help them immediately too.
Kennedy ?????? Patfull
Shaw Davis Bugg
Whitfield Shiel Kelly
Mumford Ward Griffen
Treloar Patton Hoskin-Elliot
?????? Cameron Smith
For mine they lack a genuine crumber, another playmaking half back, a reliable full back, a forward/ruck (why trade Giles?) and possibly a back up in case Mumford goes down (no idea who their other rucks are). But all that could easily be fixed up in a couple off seasons of recruiting. I think their success will come quicker than people realise.
