I would have included Martyn Williams in the back row as a) he's an annoying tosser and

he'll get the ball away from an area where the Lions have problems - at breakdowns. Wallace is a 'better' sub. Heaslip was a definite.
I also thought that Simon Shaw was in with a shout after his performance midweek, whereas O'Callaghan seemed to coast through part of the game. Understandably I'm only watching on the telly so what can I deduce...
O'Gara, Ellis and Adam Jones is also a pretty powerful trio on the sub's bench.
Good luck and let's hope for an entertaining game...but I fear "pick & go" "pick & go"...
