This graphic illustrates the record of NFL head coaches relative to the expected mean (.500 win rate) and one standard deviation of the mean. Check out how Andy Reid and Romeo Crennel compare. Here's what the author had to say about Reid: "Despite a 4-12 record in 2012, Reid did a remarkable job, winning more than 58% of his games in Philadelphia. Eagles fans never gave him enough respect because he never won a Super Bowl. The visual shows his win percentage is more than 2 standard deviations better than 50%." I'll add my 2 cents: unlike Dungy and Belichick, Reid accomplished his win rate with above average though hardly All-Pro quarterbacks in Donovan McNabb and Michael Vick.
