Joe Thornton didn’t want to admit that the 4-1 loss to Calgary on Wednesday night was a step backwards for his club, or even that it felt like the Sharks were sloppy for the first 40 minutes at the Saddledome. “Not really,” Thornton said. “You’re so consumed in the game you’re just kind of trying to catch your breath, and go back at it. Pucks were bouncing a little bit. I thought we played well in the third, I don’t think the score indicated that. We pushed and we pushed hard in the third, and just unfortunately we didn’t get the points.” Dan Boyle offered a distinctly different view. “It just sucked. It just sucked from the beginning,” Boyle said. “It just sucked, I think.” Blake Comeau and Jarome Iginla scored third period goals to put Calgary up 3-1, and anyone that’s been following the Sharks in the last six weeks probably figured that they were done for at that point. After all, San Jose has failed to score more than two goals in regulation in a dozen consecutive games, and 16 of the last 17. The one game they did reach that three-goal threshold was a 5-3 loss to Chicago on Feb. 5.
