Could be possible if that story about a club moving on their captain is true and it's about Jacko. While Jacko is a great defender he offers nothing in attack on an edge or as a middle.
Have you even considered the possibility that Jackson hasn't been offering much in attached recently because;
1. The whole team has hardly done any attacking for the last couple of years
2. The service he has been getting was trash
3. He does so much work in defence that he doesn't have a lot left for attack
4. In defence he has been covering for some others that shouldn't really have been playing NRL games
5. There has been no one outside of him on the park to draw attention, making him easy pickings for the umbrella defence
6. There has been one inside of him on the park to attract the defence, making him easy pickings for the sliding defence
How about we see how he goes with some decent players around him, then we might just get a better appreciation of his total abilities again (yes again, because I am sure he hasn't forgotten how to attack).
