Well I must admit, I'm totally out of touch with what sort of condition and level Rangi is at nowadays. Clearly the options for an experienced halfback will be limited. Going down the loan route would seem risky unless we can be fairly confident it'd for the season which might also be a challenge.
Given the choice I would probably be trying to take the safe option of Keyes who we know will fit into our side. He doesn't seem to be getting a chance with KR but 2 week loans for such a pivotal position would be a big risk and potentially very disruptive.
So yeh, I'm sitting on the fence with this one!
