It was completely baffling. Out of all the things Sando could have whinged about to the press and he chose something as petty as a 25 degree day. Even worse still, he mentioned in the presser that he told his players to ignore what he said about the weather in that press conference as he didn't wan't to give them excuses for the underperforming in the next game. Seriously that itself is pretty nuts, and admitting it to the press is even crazier.
It's a shame too because up until that point, he was virtually whinge free. I watched all his pressers and he wouldn't usually complain about anything. Even things he probably should have.
