From the Tigers I'd reckon Dan Rioli could breakout from quality small forward to star mid/forward. Whether that's a breakout I don't know. Also Higgins looks great in the preseason and could step up to genuine quality AFL in 2019.
Dan Rioli already has a decent enough reputation, so I guess it depends on whether you would class going from Good to Great/Outstanding as a "break out". As a good example, would you consider Macrae's 2018 a break out? Because he was a good / very good player prior to this year, but became elite in 2018.
Butler is one from your club I'd be picking for improvement this year, but again I'm not sure whether it'd be a breakout since he's already a decent player
Ditto on Kennedy - you don't lose talent, especially when you're a committed type who wins your own ball.
I imagine Raynor will become what Jake Stringer thinks he is. I expect him to build his tank over coming pre-seasons but he has everything else already, very strong lad who will only get harder to tackle with time.
Yeah i reckon trolling Danniher at this point in time is just injury trolling. A good player but has been restricted by injuries past two years. Bad form. As a blues supporter, i'm happy not to see Danniher out there, but not happy for the circumstances of him not being out there.
Lots of good talent out there right now.
Backing both Hopper and Taranto to step up in 2019. Taranto looks the obvious younger gun, but Hopper is now ripe to breakout and there is a hole in the midfield with his name on it.
