Agree, and don't even think it's a bias. Just the nature of the position. A forward will rarely kick 5+ nowadays which you pretty much need for max votes. Alternative is to be a high disposal/mark KPP and that is also mostly a thing of the past. You can't often justify max votes because a key forward stands up in a couple of key moments.It's always the mids in the coaches award too. As a forward, it's just nigh on impossible to star as consistently as the top mids do.
Key forwards still get enough recognition. I think still more than they deserve. It's key defenders that get the raw deal. AFL really does need a defender's award.
