Panthers coach Kevin Dineen said the team’s Achilles’ heel during the first half of the season was the team’s inability to win games in overtime. So far it’s a problem in the second half, as well. The Panthers rallied from a two-goal deficit on Friday night yet watched Dustin Byfuglien wrist a shot past Jacob Markstrom with 40.5 seconds left in overtime to lift Winnipeg to a 3-2 win at BB&T Center. Florida, now 5-7-6 since beating the Jets here on Jan. 31, is 1-6 in overtime games this season and has lost five in a row since beating the host Flyers in a shootout on Feb. 7. The Panthers have suffered five of their six overtime losses on home ice. Florida’s lone road overtime loss came in Winnipeg. “Losing five overtime points at home is tough. It leaves a little sting,” Dineen said. “You lose five games at home in overtime is disappointing for our players and for our fan base. The game had some tempo to it. Not to finish it and push it to the next level is disappointing.”
