Wouldn't put it past them. As always, there's a LOT of 'sovereign risk' when it comes to counting your future draft/trade strategy. This stuff changes EVERY year.
As for Fletch junior - lot of water to pass under the bridge yet. In 2 out of 4 of his TAC games he's had 2 touches. He was not selected in the VM squad, which tells me he's not projected as a likely top 10 prospect at this stage (underage talls tend to find it harder to squeeze into the state squads than underage mids, but the most promising usually make it regardless)
Next year is being talked up as a pretty strong talls draft, and I'm not sure where the Fletchlet fits in the pecking order. The King brothers are probably leading the pack at this stage, from vic at least, not sure what's available interstate. Being primarily a tall defender at this stage is no big deal. As a bottom-ager I'd expect that this year anyway (they normally start them back, except in the case of obvious forwards like Patton etc), though at 197cm I expect he'll have a run in forward and probably in the ruck before next year's draft. He hasn't always been a backman, he has a modest but consistent goalscoring record at Aberfeldie.
As for what he plays like - I haven't seen him yet personally,. However, thanks very much to @Dunlop who pointed this out to me, this year a lot of TAC games are ending up on youtube via AFL Vic, and MiniFletch's most recent game is here for anyone who wants to look. Haven't had the chance yet myself.
