When you look at Ernies blueprint for how he wants his front guys to attack then you you quickly see that Brockies skill set is the least suited.
. Brockie sits on the defenders shoulder and waits for something to bounce his way. He does not dribble around defenders, he does not make angled runs in behind. He has no pace. This does not mean he is a bad player. He is one of the cleanest strikers of the ball in the A-League. However he is better in a long ball side where there will be deflections and tap downs. Unfortunately for Brockie defenders have figured out if you stay goal side of him you can easily block his shooting. He won't go around you or burn you with pace.
I would expect our front three to be Kenny, Burns and Weemac(if we get him) next in line would be Krishna and Boyd. Brockie will struggle to get bench time. I think this could be Boyds season. He is still young but he is learning fast.....he developed really well under Ernie and if he continues to improve he will be a very good A-League player.....needs more goals though
Brockie is basically a pure finisher. If he was a better finisher he would be useful but he misses too many easy chances - just far too streaky.
