When Duke basketball coach Mike Krzyzewski implements any new plan of attack, more times than not it will be successful — 1,100 wins and five national championships are evidence of that. But there are no guarantees in life, and that applies to games played on hardwood.
Actually, a large part of what makes Coach K the GOAT is his willingness to adjust — rather than stubbornly adhering to his initial plan — when strategies don’t play out the way he thought they would. This was the case after he refused, for many years, to recruit players who intended to stay in college for only one season.
