If the sens fall in the 9-12 range I could see them snatching Mathew Barzal. He could be the steal of the draft since he has been hurt for much of the year with a knee injury. He has absolutely amazing vision, speed, and hands. He has been compared to Nugent Hopkins and Duchene. What I like about him more is that he studies the game, he watches hours of film, learning what he did well and what he needs to improve upon. He might not be the biggest being around 6'0 175 but he has time to grow, and his style of play doesn't require him to be large to be successful in the NHL.
Ideally the sens finish with a pick in the top 6 to draft one of McDavid, Eichel, Hanifin, Marner, Strome, Kylington.
