I'd be very happy with a 12 who runs hard, has some pace, a good step, and is solid in defence. Right now we don't have either a hard runner, or a truly creative second distributor.
Let's for a moment imagine that we had Umaga at 10, with Grigg and Loz competing for the 12 shirt, with JdJ and Fekitoa competing for 13.
I'd pay to watch that.
