I doubt there is any milage in this. Not doubting Fishers qualities but as Pete says he is a player in the shape of Monaghan, that being the case I don't see the point. Someone like that needs to start not be brought on for impact.
Hence why Lance or Lomax or Flanaghan, as they could offer a burst of running to give roby a rest. I agree Roby's impact dwindled towards the end of the year, a bit like Graham, but that happens when players do 80 minutes a week until they bust. Nothing wrong with the odd 80 minute spell but week in week out would leave even the best physically and mentally exhausted. I think Saints fan said during the season that Roby had extra time after each match to return to training to allow him to do those 80 minutes.
Nothing wrong with doing 30 mins, then letting Lance run em ragged for 10 minutes either side of half time, then inject roby back in for the final 30.
(besides didn't the club say no one else was coming in? and if we did get anyone surely it would be the phantom prop.)
