Mitchell has already been elevated. Wines a lock.
Hrovat will average 80+ if he plays. Two of himself, Koby Stevens and Clay Smith should get games with Boyd/Libba/Wallis locked in as the other inside mids (Cross too, but he will play a different role IMO). I've got Stevens over Hrovat at this stage, but all depends on who is named round one.
As I mentioned above, he won't be competing with those guys as he will be playing forward of centre.
He has been training with the forward group all pre season
