To add a bit of context to the whole puck incident: apparently Brady did something similar in December 2019 against Montreal, when Cayden Primeau recorded his first win:

Brady said afterwards that he knew Cayden from his WJC days and that he didn't even know it was his first win. I smell BS on that -- I'm sure he knew exactly what it was (whether he was doing it just to screw with him and planned to give him the puck afterwards, who knows -- but Carey Price chased him down before he went into the locker room).
In any event, I guarantee Chucky knew all about this, and whether he would have mentioned to Rasmus before the game is anyone's guess, but I don't think it's a coincidence that it happened against Ottawa.
Disclaimer: Still a dirtbag play after losing a "must win" game -- not excusing it in any way.
