These are the same doubts people had about Murphy and some even wanted him delisted, before he proved himself.I literally said in that post that he is a VFL player at best, based on his performance and comparison to players he defended in the AFL. He could grab 30 marks against anyone in the VFL for all I care. He can't do it in the AFL against AFL level competition. And there's several games and evidence of that.
And my definition of challenge the ball in the air is about preventing his direct man from getting marks or touching the ball first while ball is in the the air. So marking uncontested doesn't count.
Look at Howe, Murphy and Moore.
Those 3 repeatedly contest ball in the air well. Howe and Murphy elite in the league.
With that said, many good defenders don't have to contest marks to be good. They will need to be good at reading the plays and intercept inside 50 entries or tackle players. Dean has failed to show enough in this categories also.
He's bad.
And it would need a 180 degree turn around for him to be good enough to help Pies in a finals setting. He is a liability.
I suggest you go and watch Deans last VFL game. The opposition was very good, so please don’t deride the performance as “only” VFL.
How does he get promoted without excelling in the VFL?
