Caufield is just a machine. He's one of those guys where everyone on the ice knows what he's going to do - get below the hashmarks and blast it at the net - but somehow nobody can stop him from getting open. He's like Brett Hull in that regard, i.e., he just seems able to sneak in and evade coverage and BOOM. (Stamkos is similar in that respect too).
It helps that he has "Slick Nick" Suzuki dishing him the puck. Again, everyone knows Suze is going to be looking to pass cross-ice to CC, but, again, no one seems able to stop it. We haven't seen elite skill at FW in Montreal in a long time. That's what it looks like.
