Hobbs is definitely the most bankable & the only guy I would put money on to play 100 games. Don't think he'll be the best player from 6-15, I think one of the others with an outstanding feature will rise to the top. In saying that there might be disappointment with some of those upside players, as there is every year, whether that be a failure to lock down a midfield role or simply a player unable to keep up the pace & intensity. Here are my main contenders.
Rachele - Kicking is hugely damaging and when he gets involved there's usually a score, whether that be his own input or a score assist. He's an inside player needing some coaching with regards to his outside game - much easier to do than the other way around. Don't particularly like the Greene comparison because Toby was a mid who became a forward, his tank was also much more evolved. I see Rachele as more of a Robbie Gray type, will probably take just as long but if he does manage to cut it in the centre square he will surely add a silky component. Downside is he never builds the aerobic capacity but not a terrible floor if you consider the importance of Heeney, Gray, Greene etc.
Goater - He's the one with the extreme break away speed so the sky's the limit if he nails down a position in the midfield. Kicking not overly important and he's a much better kick than Dangerfield & Fyfe, it maybe an issue if it's a significant drop below Houli but he's a better kick than McIntosh so the downside doesn't fill me with dread. His leap could also be a serious weapon and I see hangtime written all over him. Fantastic project & a player who you would probably want to throw around the park a bit until he finds his niche. Pretty much needs to be dealt with in a similar manner to Balta and given every opportunity to grow & gain confidence.
Johnson - Elite agility, very good kicking, imposing frame - plenty to like about Johnson and I suspect he'll thrive in an environment supported by elite clearance players. Most will disagree with me but he definitely projects as a dual position prospect given his height & build. All the stuff he needs to work on can be taught, the basics like spoiling & running off his man will come with experience. I don't have his sprint time but I have never viewed him as slow or crab like, he generally puts the team in a better position. Could also be a forward threat if he grows another couple of centimetres.
Erasmus - If you are confident in Colts then he's a star in the making, good overhead, a good turn of speed & dangerous around goals. His height puts him amongst the elite and with a few preseasons he will be strong enough to match it with seasoned players. My only concern is the fact he hasn't been tested at the highest level, the Geelong reserves match illustrated just how far behind he is in matching the physicality. Nothing overly concerning but I would be careful about reading too much into Colts given his Academy preparation puts him at a significant advantage. There could be a bit of foxing going on in the West, there appears to be a fair bit of that occurring all over the country but I'm not entirely sold on Erasmus & would prefer to leave him for our third pick.
