Harley doesn't play for three or four games, which suggests its a fairly minor calf tear injury what ever. Injuries happen so we turn the page and welcome aboard L Weller, or one of the other string of new untried mids/ forwards. It has to be a new untried player, because we know what we are going to get from those that have been getting regular games over the last five seasons.
Why not throw A Pearce or S Collins onto a half forward flank. Both are mobile and can play either end of the ground. I would even like to see A Pearce play in the ruck, as the dogs don't seem to play one against us and he would create great pressure in the midfield once the ball had been bounced and come to ground. So its lips off the ground, heads up and lets see who wants to play.
