Haula scored for the third straight game to cut it to 3-2 at 13:49 of the second period, getting a rebound at the top of the crease on the power play.
"Today was a [terrible] game for us," Stamkos said. "Unless we change things, it's going to be a really, really long year. We rely so much on our goaltending and our power play and the passing. It's three games into the season, that's the good news. There's lots of times to correct these things. I don't want to get too down, but it's frustrating knowing the group we have in here and we keep continuing to do the same thing and expecting different results."
