I think @Longinthetooth nailed it around this time last year. “What is a villain?”
Violent = Imposing will
Instinctive - Nose for the ball
Love of the game - passion to play
Leadership - on and off the field
Awareness - play recognition
Intelligent - learn and retain information
Nasty = grit
I think all of those boxes have to be checked. Then other things like production are factors but not deal breakers.
