Except we don't have another average guard on the roster according to PER. Look at Kalebs PER when he plays, or Howards. I mean we can cherry pick stats all day, but by win shares Cooney has contributed the third most to this team. Malachi's PER for the season is pretty much the same as Cooney's, and he's contributed less win shares.
If you want to go to Conference PER, The poster responding to you has a good point. Mike has been awful. 8.0 Per in the Conference season. Worse than Trevor.
Per is an ok stat I guess, but it really doesn't take into account players responsibilities on a team. Obviously Mike has more responsibilty than Trevor, but PER doesn't measure that. I love analytics too, but they do not tell the whole story. If they did, Draymond Green was an average player last year, and Harrison Barnes and Andre Iguodala were below average (as their PER's were all around 15 or below). Any NBA fan would laugh at that notion.
