"it's very unsettling and I feel bad particularly for a few of those struggling and with limited minutes."
To be fair; that's a lot of those players own fault for choosing to go to MU and/or because their simply not good enough for more minutes (Odigie, Milner, Adnam).
I don't know who you're referring to specifically but i'd imagine Wesley would be upset about his minutes - but again, classic example, he chose to go to Melbourne and did so after MU had already signed Blanchfield, Majok and Barlow (who can all play his position) and they still had imports/big time locals to sign up.
He should have expected he would have to fight for his minutes - funnily enough, he is playing about 18mpg currently; his last season in NZ he played 25mpg; dare I say it he would probably be playing 28-29mpg ish for NZ this season if he was there.
