Daly and George will go to NZ. George is the best hooker in the NH right now and has been for a good 12 months at least.
He's certainly the best English hooker. I can't remember how many hookers are usually included, if it is four, then I think he might be in with a shout to come off the bench. If they only take three, then I don't think Gatland will choose him over Owens, Best and Hartley. By the time the next 6N rolls around, I don't think Hartley will be a starter for England, albeit, I think Jones would be reluctant to dispense entirely given the amount of caps he has acquired.
