FORT LAUDERDALE — Talent? They have it. Purpose? They honed it. Scars? They have those, too. One heady season after the Florida Panthers surprised everyone by climbing from the lowest seed to the Stanley Cup Final, they’re ready to do it a different way starting Sunday with Game 1 against the Tampa Bay Lightning in Sunrise. They’re a prime team to beat this time. “We know what we can do,’’ captain Aleksander Barkov said. Everything’s before them on the table now. “This is the time we’ve looked forward to,’’ top scorer Sam Reinhart said. The Panthers are either the favorite to win the Stanley Cup, according to Vegas oddsmakers, or listed second behind Eastern Conference rival Carolina.
