Somerby is a defenseman converting from the forward position. At 6-5, he is a big player who is still growing into his body while at the same time trying to get comfortable at once again playing defense. He is definitely a project pick, but one with some interesting upside if he can complete the adjustment and improve his overall skill level.
Somerby is in his freshman year at Boston University.
