Not to be ignored is the addition of forward Sam Reinhart, who's arguably a first-line player. Along with linemates Mason Marchment and Eetu Luostarinen, the Panthers' third line has provided considerable production early on, combining for five goals.
The Panthers' two pillars on defense are Ekblad and MacKenzie Weegar. They play in all situations and are one of the best defense pairings in the League. On the second pairing with Radko Gudas, I see some more found money with the way Gustav Forsling is playing.
With seven assists in nine games, he's utilizing his biggest weapon, speed, to fuel quick transition and offensive zone activation. His ability to close distance is also noticeable in eliminating time and space for the opposition.
With all that depth, Florida's style is a little different than Carolina's, but no less successful. Their forecheck relies on pressure, stick positioning and anticipation more than physicality. Marchment throws the body around but he's really the only one. The reality is they don't have to because they have the puck most of the game. It's a small sample size but Florida is generating chances and has the best shot-attempts percentage, 56.0, in the NHL.
All that said, one of Florida's biggest strengths this season that was less so last season is that the real Sergei Bobrovsky has showed up (6-0-0, 1.81 GAA, .944 save percentage). The goalie is locked in and appears he wants to silence his critics. Spencer Knight (2-0-1, 1.95 GAA, .929 save percentage) has also played well. Goaltending has been a huge benefit for the Panthers and helps to build team confidence early.
The Panthers do, however, have a unique challenge in front of them with Andrew Brunette taking over after Joel Quenneville resigned as coach in the wake of the Chicago Blackhawks' sexual assault investigation involving Kyle Beach and then-video coach Brad Aldrich. With Brunette, they will have consistency in messaging, which is important. They do have a crucial decision on who will lead this team moving forward, but the goaltending, the possession numbers and the eye test all lead in one direction, that Florida appears to be the real deal to me.
