Photo: Rob Carr Steve Mason knew the questions were coming. He did not hide from them. For him, the only way out of one of the most embarrassing moments of his life was through it. “I messed up,” Mason told reporters after a 4-1 loss in Game Two of the first round against the Washington Capitals. Less than two and a half minutes into the second period, Mason allowed a rolling ground ball to pass through his legs. Mason had made an impressive save a minute earlier, possibly tweaking a muscle, but he denied that played any part in what happened next: a puck deflected by Jason Chimera at the redline that slid into the back of the net with Mason frozen in place. “It’s my fault and I realize that,” Mason said.
