If you hate Duke, prepare to be infuriated:
You can discuss in the comments, but just food for thought. For some reason, this whole discussion is couched in rhetoric about Krzyzewski's performance "leading Team USA to Gold" and I'd just like to note two things. First, I can't remember another coach getting anywhere close to as much credit for leading Team USA to a Gold medal, and second, Coach K probably had the most talented U.S. team since the Dream Team.
As for his performance with Duke this year, well, they won. So it's hard to argue he didn't do a great job. But does that really put him in the discussion for the best coach in any sport?
