I'm intrigued re: Duke for the same reason (although obviously less mature). Coming from bush footy to AFL is a fair ask, but he seemed to adapt well. He obviously has the size for AFL - can't wait to see him add strength* through an elite programme & build his tank.If Bramble has a strong and injury-free pre-season and develops as one would expect a slightly maturer player with a first proper pre-season under his belt, and with the support and belief he clearly has from Collo and Sammy, I don't see how he is not best 22.
*could probs even drop a keg or three whilst gaining strength.
Nash is the other one who I think can improve over Summer, for the same reasons you provide: proper pre-season (as a midfielder) & the support & belief he has from Sam. Could be another really good find.
And both (essentially) freebies.
