We're upset that we don't have Wade to help create magic, and scare defences into being a bit more thinly spread, but then think we don't want Naholo? I think he could be very handy coming in off his wing, he's not slow either. I'd be happy to see him, equally I'd not be too upset if he didn't come. With Fekitoa and JdJ as centres, I think we'll be fine there.
I do worry about the EQP numbers a bit though.
As for Gatland, why not? He's a very solid coach, he's adaptable to the personnel he has, and seems to be embracing a more attacking philosophy with Wales. The only question is the relationship between him and Dai, or Dai is leaving. I'd be upset with Dai going, but Gatland coming in would neutralise that.
With the ever increasing Highlanders influence, I'd not be upset with Jamie Joseph, or even Aaron Mauger either (Mauger to act as head coach under Dai DoR though I think).
