I'm not informed enough to prefer Sonsie or Chesser in that role, but would be happy with any of them at that pick.If it's wing/mid they're picking at 21, Sonsie and Chesser are still there. Wilmont makes no sense.
Also, DIb isn't an upgrade on Western - and Western struggles to get a game.
Western isn't struggling to get a game. He got a debut in his first season and would be way ahead of expectations.
