Will be interesting to see what Wayne does with the pack once Aitken is back. He may well start Aitken off from the bench but even then, he'll come on and play edge shifting probably Keaon into the middle rotation. Aitken is a left edge player whcih is where Keaon has shifted to this season after previously playing on the right side but being a bit of a defensive liability there in the past. He is a lot fitter this year of course, Keaon, but he has done really well on the left.
Meanwhile, Arrow, who could easily transition back to the middle rotation as can Keaon, has been immense defensively on that side sliding well with Graham to limit the damage which we missed for parts of the game against the Dragons when he went off twice for HIAs and couldn't come back on after the 2nd one.
Personally, I'm thinking Keaon to 13 when Aitken gets back to full fitness and Duncan back to the bench rotation. Wayne didn't bring Aitken over to be a bit part player either I'm guessing. Could work well. Keaon exploded into awesome form last year when he shifted to lock.
Will be interesting when we get more troops back and get close to fielding a full side in a few weeks time - providing no more injuries or suspensions happen in the meantime - fingers crossed!
