George Karl has been coaching since 1984, where is the hall of fame player he has had? Maybe Melo makes the hall of fame some day (yet to be determined)
Mike Fratello coached 16 years and only coached one hall of fame player (Wilkins).
Don Nelson coached 34 years, I think the only hall of fame player he had was Patrick Ewing and he has him for a whole 4 months and he faught with him the whole time and quit/got fired over it. I can't name another hall of fame player Nelson ever coached in 34 years!
Your argument is based on your memory...and you may just be too young to actually remember some of the guys these coaches had on their roster.
In addition to 'Nique, Fratello also coached Moses Malone for a solid 2-3 year run in Atlanta. Still, The Czar is definitely the best support for your argument.
George Karl coached surefire hall of famer, Ray Allen, in Milwaukee, plus guys like Melo, who will likely be in when he retires, and guys like Gary Payton and Chris Mullin, who I expect to see enshrined within the next 2-3 years.
Nellie coached a significant number of hall of famers, from Alex English and Bob Lanier up in Milwaukee to more recent players who likely will make it when they retire, like Steve Nash and Dirk Nowitzki.
Look, I get what you're saying...I really do, but my point of "If you coach for more than 20 years in the NBA, you're bound to get a couple of hall of famers" is valid as well. The bottom line on Sloan is that he built a consistent winning program in a place where nobody worth a damn would choose to go play, and he did it by building disciplined "good fundamental" teams.
Jerry Sloan was a great coach...period.
