With scrum half, Eddie wants most box kick accuracy (and absence of charge downs), evidence of direction change, and fast breaks and supporting play.
Last night, Porter was all these things. And then Dobbie came on and proved how MUCH better than him Porter was against the same opposition (and thus a direct comparison).
Eddie has a ton of back row players to choose from, and a 10 MUST have 90% points kicking ability, which Atkinson does not.
So, was he there to look at Porter? Maybe. Otherwise, I think his eyes were on a Bath player or two.
