Penguins Prospect

I was reading www.pittsburghpenguins.com yesterday and they had an article about Casey Pierro-Zabotel a center that we drafted in the 2007 draft. He is 20 years old 6'3" 205 pounds and has 27 goals and 61 assists in 49 games for the Giants of the Western Hockey League. Those numbers combined with this guys size have me pretty ecited. According to Caseys coach who was and NHL coach he believes he will be playing in the NHL shortly as a first or second line center. My only skeptacism is if this guy is as good as they are leading us to believe why isnt he playing for the baby Pens right now. And if he does prove to be as good as they are saying and he makes it on the Penguins roster in two years, where does he play? Do we trade him or Staal or do we give him a chance to play wing?
