Again said with trepidation, but what is the difference between 7 and 6 these days anyway?
There is no real skill to feeding the scrum as such.
Both positions need a kicking game, distribution game, running game.
For me we could sign / develop two stand-offs and just interchange them.
If you unearth a Rob Burrow then yes you'd put them at 7 to somewhat protect them, but otherwise we just need two skilful, creative players in the halves who are good all-rounders.
Re Myler I've just not seen enough from his game this year in particular to make me think we should keep him. He's a nice lad (again) but his kicking game has been awful most of the time, and it's just not good enough I'm afraid. Yes, we've been on the back foot too much for him to breathe, but in every game we do apply pressure he fails to nail the last play time and again.
