It’s easy to see why Matt Cullen believes that at age 36 he is in as good shape as he has ever been in. With a water bottle in hand, the svelte Cullen took a break from touring Nashville to meet with local media Friday. The Predators signed the former Minnesota Wild forward July 5 to a two-year, $7 million contract and indicated he could be the first-line center in the season opener. If that is indeed the case, Cullen, who had seven goals and 20 assists last season for Minnesota, sounded eager for the experience. “As a competitor and an athlete, you always look for those situations to do more and make an impact on a game, on a team, and on a season,” Cullen said. “I’ve played a lot of hockey and feel like I have enough experience now where I’m comfortable with whatever is thrown at me, and I’m looking forward to any of those challenges.” Cullen has long been known as sort of a jack-of-all-trades center with excellent speed, but hasn’t been a big scorer. His career-high for points is 49, which he hit in 2005-06 and in 2007-08 — the latter was in just 59 games.
