It is not up for debate that Hughes gets the easiest minutes of the three.
And yes, the stat does punish players who play lots of minutes but don't necessarily score during them. That's whole point of the stat. It controls for players like Hughes who play lots of minutes, gets favorable deployment, and shows how efficient/effective/offensively dominant the player is relative to peers.
I'm no longer interested in this conversation. But I do look forward to his upcoming turn in the barrel when Vancouver fans/media pivot from hilariously overrated him to demonizing him for made-up reasons.
