Patrick Kane was drafted by the Chicago Blackhawks with the first pick in the 2007 NHL draft. The season before he was drafted, he spent that time in the OHL with the London Knights. Kane didn’t go to college. He made the tough decision to leave home because he wanted to become an NHL player.
Whether Kane went to college or not, he still would have gone number one in the draft he decided to declare for. If anything, a college Kane might have put up even better numbers than the unreal OHL Kane we witnessed.
