No we don't Aries.
the 5/8 and the halfback together play in the HALVES.
the same way that the centres and wingers play in the THREE QUARTER LINE
and the fullback, he's just the fullback
IN australia, as we have been doing in this forum since it began, we call the number 7 the HALFBACK, and the number 6 the 5/8.
Never, Ever, was fittler referred to as a HALFBACK. Nor Daley, Lewis, not even the wanker from st george Barret is referred to as HALFBACK when playing in number 6 for his drag'ins. But it was always news when he was selected at HALFBACK ( number 7) OUT OF POSITION in a test team.
Similarly, Ricky stuart, Aflie LAnger and Andrew johns are never considered, or called stand offs, or 5/8s, or fly halfs.
The two positions are totally different and have always been called as much.
