Marty Turco. During his 4 years at Michigan he was underrated as an athlete and much of his success was credited to the great teams in front of him. But if you watched him closely you could see by the time he was a senior NOTHING rattled him and he always made the saves he needed to get the win. No way Michigan wins the 1998 NCAA title without him. Him and Ryan Miller are the only 2 NCAA goalies I've ever seen live I thought would have a shot at being a #1 NHL goaltender. Obviously Miller is still a work in progress.
Jason Allison - Was the best player on the London Knights for a long time... I was actually surprised to see how long it took him to become a great player in the NHL; he kinda bounced around Boston and Washington before getting really good in L.A.
Not exactly stars, but three players who dominated in North Bay are:
Alex Auld: he backstopped a horrific Cents team to respectability.
Vitali Yachmenev: was the best player on a OHL champion Cents team. Could score almost on demand.
Igor Valeev: probably the most exciting player ever to grace North Bay Centennial colours. I'll never forget a game in which he scored three highlite reel goals, then the very next shift kicked the *blank* out some guy in a fight.
