I could see either AJ or SJ doing well for us... or failing dismally.
I think SJ is less of a risk but will have mediocre games where we lose because our half does nothing... and other games we win because he steps 5 people and scorers or assists.
In saying that my preference for halves is Moylan to stay, he really started to look good, so SJ is a no from me. I can't imagine Flanno replacing Chad pushing his own son another spot back.
AJ would have to come reasonably cheap to be worth the risk and if he doesn't make the team he doesn't make the team.
