That should be no surprise, really. Tanev is the best forechecker with Perreault on this team. He may not have the softest hands or highest hockey IQ, but he brings an element to the Jets checking line that is really a crucial part of hockey, and he brings it every single game.
I'll use your post as a jumping off point PS....
I agree that Tanev is a very important part of this team, so is Lowry, so is Hendricks etc. It's a team sport and this team seems to be built to be very complimentary of each other. Every single player on this team is bringing something valuable. Not everyone is a tasmanian devil or a speedy gonzales, and not everyone is a world class scoring machine or a member of Hockey Mensa, but they all contribute in their own way and they are all equally valuable.
I have a newfound respect for Maurice, Chevy and all of the players who I doubted over the past little while. This team has so many pieces integrated beautifully, that are also somewhat interchangeable (Connor/Roslovic 1st or 4th line???? MP playing everywhere????) .
All of this without our best forward and a top pairing D, and Kulikov.
They won't win every game, but it's a joy to watch win or lose.
