You guys will like Hyman for the first few years of the contract. He's a guy who shows up every shift and retrieves pucks like no other. What he lacks in skill, he makes up in heart.
There is next to no chance he ends up like Jamie Benn. If those are your expectations you'll be sorely disappointed. Hyman is a very low skill player who earns everything he has. He could have settled to be a regular 4th line tweener, but instead willed himself into a top 6 player.
The biggest question mark is how long he can keep it up. Injuries have started to creep up on him and, with his style of play, could occur more often. I have a feeling that once his health starts to fade his game will regress very quickly due to his lack of skill.
Best of luck to him! He was great the past 2 years!
