You’re right not black and white.
No one can foresee injuries, specifically severe ones.
The difference is Kirby before he even got here didn’t show he was a legit C and in his time here that has continued. He is brutal at the dot, and very lackadaisical in his own end.
Showed some returns sure playing with Nick, most do. I will agree if he turns this around (even as a wing) then I’d be ok with the trade but so far I don’t like his work ethic or intensity one bit. If you can’t score, work your tail off without the puck, he doesn’t do that. That’s the difference between him retuning from an injury and CC returning.
time will tell, I hope I’m wrong for the habs sake.
