Letunov and Thompson are two different players.
Letunov is a playmaker.
Thompson is a power forward.
Thompson's game will improve year after year when he puts on more weight and muscle. His game relies more on his physical strength than Letunov's.
Letunov's game does not rely upon his physical strength as much as Thompson's does because of his playmaking ability. Letunov's playmaking ability allows him to overcome his physical shortcomings. Letunov's speed and strength does need to improve to play at the professional level but it will come over time.
It will be interesting to see if Letunov stays beyond his sophomore year. He will leave a big hole when he does leave. A team of juniors Letunov, Thompson, Gendron, and Masonius and a large senior class could be something special. Of course, it depends on who the goalie will be at that time. Whoever is recruited to be Nichols' replacement will be the most important recruit in the near future. Maybe Matt Ladd, who decommitted from Niagara, is a possibility. Heard Hockey East schools are interested in him. Playing at Avon Old Farms this season.
