This was the last preseason game the Lightning and Panthers played in Amway
Bogo fought Marchment, Serge fought Bennett, Perry fought Tippett, etc. but imo maybe the most important one was Katchouk initiating a fight with Bennett. Definitely felt like that was the moment Katchouk won his spot. It earned him the respect of the veterans in the room.
Coincidentally Paul said something yesterday that I including in the op about making sure you could trust the guy next to you on the ice. So we'll see how this 3rd period plays out. Maybe there's another Katchouk like moment coming up in this game.
