I think Johnstones affected our play pretty well, he's sped up the play the ball and contributed more in attack than Houghton does, as well as being pretty solid defensively , there's nothing really not to like about how Johnstones played. I'd say yes Johnstones been better than Houghton which is why he's now starting hooker, I'm pretty sure Last agrees and probably a big majority of Hull fans.
I've posted previously about Houghton not being at the races especially under Radford, no coincidence their was an article about how Houghtons frame of mind could of been better, il also say Houghton seems to of sorted his demons out and is playing some good rugby in a role that suits him under Last. That role is off the bench against tired defences scooting from dummy half, it will never be as a ball playing hooker or as a creator.
Spot on from Andy Last, why change it?
