Provorov seems to be a bit underappreciated around here. He has been relied upon heavily at a young age playing a very difficult position, and has all the makings of a legitimate #1 d-man for years to come (health permitting) imo. He might not be exceptionally talented or elite at any one thing, but anytime I see this guy play he strikes me as a really well-rounded player and an absolute horse on D.
Hamilton looked dominant before the injury and he is definitely more of an offensive force, but I'm not sure he'll be as consistent moving forward. He may be better at his absolute peak, but for some reason I feel he is less likely to stay there for long. This is also a big injury to come back from.
You can't go wrong but I'd take Provorov.
