I'm honestly not trolling, just sharing my opinion, which many Bruins fans don't agree with (but many do).
I've wanted Carlo traded for many years. He is frustrating. Overall he is decently solid, but outside of a few moments or periods of time, he always leaves me wanting more. Nothing about his game is that great. He doesn't use his size, he isn't physical, he isn't fast, he doesn't have a great stick, doesn't have a great hockey IQ, isn't a great passer or playmaker, and has a terrible shot, both in the quality, power, accuracy, and IQ of the shot. He has been very frustrating to watch on this team. Plus the injury tendencies.
Overall pretty solid, but just not really that great at anything, and can be frustrating. He is also just way too nice, pretty much zero grit.
