Said this over and over again, Jackson is the type of player who can be a useful piece in a good side, abit like Tim Glasby, Kenny Bromwich, Mitchell Aubusson, etc.
If he's in your top 5 players than to me you're not a contender. When he came into the side found himself in an ideal situation with guys like Graham, Pritchard, Klemmer, Eastwood, Kasiano, etc around him, he wasn't expected to lead the pack, wasn't expected to make those tough hit ups from his own line, wasn't expected to set the tone, he had a fairly easy job, tackle, take the 3rd or 4th hit up in a set and be in the right position in attack if the ball came down his side.
