He's not playing with Ceci anymore, no one is playing with Ceci anymore, and everyone is playing better.
Kulak is playing like a legit top-4 defenseman and he and Nurse are playing great hockey together. Nurse is playing like a #2/3 defenseman and might be displaying his best all-around game ever.
Stetcher is providing a ton of grit and playing quite well and Emberson is basically a different version of Desharnais (imo) who skates and moves the puck better, without Vinny's size and strength (he's no slouch, but you know)
The players have improved their games, but one guy that was (as people like me were screaming) was a milestone around everyone's necks is on a different team, and also everyone is playing better.
It's not ALL Cody Ceci, but Cody Ceci was clearly part of the problem, him not being here is a significant part of the solution.
Hartman is a general dirtbag, and I don't think he's that smart.
Plus, stuff like that just happens, remember Klefa and the random broken foot lol.
He has a history of playing like a rat.
