I don't think you have to fat to be unfit or vice versa. I was at the game and it was noticeable that we quite often we ran out of available players away from the ruck or maul by the 2nd or 3rd phase (or players completely out of position).. and it was noticeable a few players were blowing by halftime.
Maybe that's beause were were defending more than Edinburgh. Its sounds obvious but fitness is a massive part of the game because it determines how effective the ruck after the tackle is (i.e. supporting players), players getting back into defensive position (i.e. falling off tackles) or supporting breaks made.
Saracens wouldn't be able to employ their blitz defence all game if they weren't surpremely fit.. a scuffle broke out during the Sarries v Munster game when a coach called Jamie George a fat *£$%... would he be a british lion if he was unfit.
Maybe Sarries take different vitamins to the rest of the EPL club players.
Coincidently Dan Baugh is leaving at the end of the season. I knew nothing of his background but apparently he played for Canada/Cardiff, his career ended prematurely and he seems to have then been with Dai as a coach when Dai moved to Wasps.
Did he fall into the role of fitness coaching simply because he was there and available and there was a sense of loyalty from Cardiff and Dai.. or has he taken a degree in sports science and nutrition that made him a viable candidate?
Anyone can shout at players to lift more or run faster in training that doesn't automatically make you an expert on strength and conditioning.
Out of desperation are the players being over trained?
