Emerging trends in the early days of the NHL season:
The Panthers pulled within one on Brown's first of the season at 6:20. Florida connected it simply over 2 minutes later when Dadonov transformed Huberdeau's pass on a two-on-one.
Down 2-1, the Panthers tied it for the 2nd time in the second period at 15:15 when Weegar got himself open in the slot, took a feed from Barkov, and beat Rittich on his blocker side from 40 feet out.
Calgary had actually taken the lead at 11:59 of the second when Tkachuk nicely transformed a give-and-go with Michael Frolik, who also had the main help on Tkachuk's third duration objective.
