Steve Mason. He's prone to some big gaffes, but on the whole, he's an excellent goaltender.
Josh Manson. Excellent underlying numbers, very solid defensive defenseman.
Tyler Pitlick has come out of the gate hot after finally getting healthy. Looks like he'll become a valuable complimentary player for the Oilers.
Stephen Johns is developing in a very good two way defenseman for Dallas. Don't see anyone talking about him.
Carl Soderberg is as solid a middle 6 center as there is. Adds a lot to a PP.
Jake Gardiner is a legitimate first pairing defenseman, Leafs fans have been touting him for the last few years but everyone is "LOL Leafs" when his hype is actually legitimate.
Victor Rask. Extremely noticeable every time I watch the Hurricanes. He's developing nicely into an average 1C/elite 2C.
