Personally, what I find is that Matthews plays a very strong game positionally.
Yes, you can usually find him on the right side of the rink, usually about 20-30 feet from the opposing goalie.
He's not often too far ahead or too far behind the play, and is able to see the play developing and get himself into the right position to make good plays. I don't find he's a generational skater like McJesus, or a super creative playmaker like some I've seen in the past (and Marner today),
He's not a great skater (nor was Gretzky) or very fast. I don't see him carrying the puck much or making passes.
nor do I necessarily see his shot as being the very best power-wise (like say Ovie). He's above average in terms of accuracy, not exceptional,
He has a really quick release which is deadly from 20-30 feet out but not a long ranger power shot. I once saw Jacques Lemaire score from about 60 feet out with a blazing slapshot on Tony Esposito.
