Great news! Tinordi has shattered my expectations this year in Hamilton. He's been great all year, so it's well deserved.
For those asking about his physicality...if you're expecting Pronger, than I think you need to readjust your expectations. Tinordi has been more focused on my playing simple, but yet extremely effective hockey. That doesn't mean that he isn't mean though. Not much of an open ice hitter, but very mean in front of the net and is usually the first guy involved in scrums or standing up for a team mate.
As for the fighting, he has some work to do there. His technique isn't awful, so I think that most of his "issues" are linked to mass. He needs to improve his strength, but that will come as he adds weight. There's certainly potential to be a better fighter, but I don't think he'll ever be as crazy as his father was.
Whether you think Tinordi is a good fighter or a bad one, I think we can all agree on one thing - if he lives up to his potential (top 4, heavy-minute eating defenceman), he shouldn't be sitting in the box for fighting goons anyway. He'll be way too valuable to the team to be doing that.
