Only hours before Friday night’s game against Vancouver, Predators coach Barry Trotz talked about trying to find the right balance between offense and defense for his team. Consider the search still underway following the Canucks’ 1-0 victory over Nashville in front of a sellout crowd at Bridgestone Arena. The Predators’ defense, which had surrendered a combined nine goals in its two previous games, returned to its stingy form of old, surrendering just the lone goal to Vancouver. But Nashville’s offense, which had come to life in recent games, also returned to familiar form. The Predators mustered just 10 shots on goal over the last two periods and were shut out for the fourth time in 18 games this season. “(The balance was) not good enough to beat a very good team,” Predators coach Barry Trotz said. “We didn’t put 60 minutes together. We played a good 20, then for the next 30 I didn’t think we played very well. “We got scored on and then we started to kick it into another gear. You need to kick it for 60 minutes and we didn’t get it done.”
