Big frame, good foot speed, overpowers your average WHL defender. At 16 (last year) he led his team in points/goals, and was the first player to score 30 goals in the WHL at 16 years of age since Patrick Marleau in 1996.
From the game i saw him play, he looks a lot like Devin Setogutchi, and with his first year numbers he definitely has the potential to be the same quality player. Helps that he is the best WHL forward of the draft.
As for proffesional opinions:
“He puts the puck in the net, he's got good size, great on-ice awareness. He's not a crasher or a banger, but he finishes his checks. He does everything well." -Peter Sullivan (NHL central Scouting)
"Brett is a very gifted player and it's too bad we haven't been able to see more of him this season because of his injury. Brett can take over a game with his skill and puck control and he's also a very intelligent player. He has always been a dependable player at both ends of the ice, whether it be five-on-five or on special teams and he's a real competitive kid. When the game is on the line, he wants to be out there to make a difference." -Head coach Dean Clark
As for injury risk, i got nothing.
