Bigras is one of this year’s most intelligent draft prospects -- both on the ice and off. He was able to maintain an A+ average in his high school studies, but most people in the league have been impressed with the way the blueliner thinks the game. He has great hockey sense and vision. Bigras can be counted on to make the smart, first pass, but will not impress you with flash. He’s poised, refined, and patient with the puck and has a game whose success is predicated on positioning.
