I gotta go with Murray too. Every time I see that kid play (Nike Hoops Summit scoring 30, Averaging over 15ppg in the PanAm games for Canada), he seems to find ways to score again and again. He also seems to thrive at clutch moments, making him a natural leader.
Having said this, I still think the guy we need to step up most is Alex Poythress. We don't need him to score 15 points per game or anything, but if we get 10 a game from him, along with around 7-8 rebounds, we're in business. We already know he has freakish athleticism and excellent strength, we just need consistency.
I think our scoring leaders early in the season will be
#1 Murray
#2 Ulis
#3 Poythress
#4 Labissierre
#5 Briscoe
Later in the season, I expect to see leaps from Labissierre and Briscoe. I also expect at least one of Matthews, Mulder, and Lee to provide more scoring than expected. Mulder may be the best pure shooter on the team. Matthews may be our most athletic wing. And we know that Lee can make some highlight plays as well. I'm excited about this team.
