He told NHL.com in August that he was going through bouts of performance anxiety that would lock him up and not allow him to perform.
That's gone now.
"It's always a little bit nervous before opening night and maybe a little bit more, but at the same time I'm confident and energy-wise I feel great," Hedman said. "It's going to be a lot of fun today."
The 35-year-old defenseman also returned to Tampa Bay in August 16 pounds lighter than when he left, dropping from 244 pounds to 228, a result of a change in his training and diet so he could be, feel and play lighter.
"As you get older the less mass you have to move around the faster you feel," Hedman said. "That's kind of been the feeling for me throughout camp.
"Bottom line, I don't think I lost any power or strength in that regard. I'm still quite heavy for this League so boxing out and winning battles is not going to be any different. But hopefully I feel as light as I am today and just get moving on my skates. That's my biggest strength as a player so just have to use that."
The noticeable difference in Hedman's physique initially caught Lightning coach Jon Cooper off guard.
"He was ripped," Cooper said. "Not that he wasn't before. It was just he definitely had a goal in mind, and he looked after himself."
