TAMPA — Center Brian Boyle said he and his Lightning teammates should have crawled out of bed angry Thursday. They had a chance to take the first game of the Stanley Cup final but instead face a 1-0 series deficit because of a timid third period that still stung hours later."(You) can't wake up in the morning having some regrets that we were a little too passive," Boyle said.But that was the feeling that lingered at Amalie Arena on Thursday, a day after Tampa Bay's 2-1 loss to the Blackhawks.Even in defeat, the Lightning was pleased with its early aggression. It had 10 of the game's first 13 shots. Tampa Bay outshot Chicago 10-7 in the first period. It took 14 other shot attempts that were either missed or blocked; the Blackhawks had four.The Lightning controlled the puck, winning 14 of the 20 first-period faceoffs. Wing Ryan Callahan said the Lightning executed its defensive plan well with strong checks that limited Chicago's time and space."It was pretty much a perfect game plan the first two periods," captain Steven Stamkos said. "We come in with a one-goal lead into the third. The first thing on your mind is to defend that lead."The Lightning dropped back instead of pushed forward."To be honest, a little bit of human nature might have taken over," coach Jon Cooper said.That's when the Blackhawks capitalized.Chicago sent five third-period shots at goalie Ben Bishop before the Lightning recorded its first shot, on Callahan's breakaway 11:38 into the period. The Blackhawks had more shots (8-5) and attempts (21-9) than the Lightning in the final 20 minutes.And in the last seven minutes, Chicago scored twice in 1:58."I just think we sat back a little bit too much, protecting the lead instead of playing like we did in the first and second periods," defenseman Anton Stralman said. Although the Blackhawks didn't get many great looks, Cooper said the Lightning turned the puck over too many times in its end.When Lightning wing J.T. Brown failed to corral the puck and get it out of the defensive zone with the scored tied at 1, Chicago forward Antoine Vermette ended up with it. His wrist shot past Bishop at 15:26 made Chicago the first road team in Stanley Cup final history to make a third-period comeback and win Game 1 in regulation, the Elias Sports Bureau said."They had it too much," Stamkos said. "The rest is history after that." Contact Matt Baker at email@example.com . Follow @MBakerTBTimes .
