The encouraging thing was that it seemed to motivate him to play with more control instead of trying for a miracle.Indeed. Cam's game was selfless team first effort. This is a new Rayner that may just be the makings of him. We have seen how Berry's midfield game has been elevated by the extra responsibility of tagging the opposition's best midfielder.
Well the Rayner progression to an A grade midfielder may also be a tweak to the mindset and given specific non glamorous team first tasks. The interesting thing, which was pointed out to me, in the first half Rayner had the third best "Supecoach" score yet he only recorded eight disposals. That meant he was doing the extra non glamorous team first grunt. May it continue.
So there's hope. Learn to keep doing the humdrum contributing team things and build yourself into a stronger more reliable unit.
