Cotchin and martin went missing in the second quarter when the game was won and lost, which historically has been a big problem with Cotchin. Its your leaders like these two that you need to play 4 quarters of footy to win those sorts of games and reignite the rest of the side when the momentum naturally swings the other way.
This was a notable factor in the loss, along with a few players who shouldnt have been out there, less tackling pressure than usual, wrong option handballs, kicking for goal, the umpiring and the lack of a genuine second tall.
