If you could assemble a superstar, Frankenstein-style, from Andrews's patients, it would have repaired knees from quarterbacks Peyton Manning and Donovan McNabb; a hip from dual-sports sensation Bo Jackson; shoulders from Michael Jordan and Charles Barkley; and elbows from the New York Yankees' Andy Pettitte and the Chicago Cubs' Kerry Wood. "I've always liked fixing people," Andrews says. "I want to get these athletes back to doing what they did before."

Because Andrews treats players on nearly every team and in nearly every sport, his reach is greater than that of any athlete, coach, or even commissioner. The totality of his work — redirecting careers, changing the fortunes of teams, even cities — makes a compelling case that he's one of the most influential figures in all of sports.

Only a fraction of his patients have been identified in published reports. In an analysis of 40 baseball players who are known patients and whose salaries could be obtained, Andrews's career-extending work has led them to garner almost $1.3 billion in guaranteed money. Ten NFL quarterbacks whom Andrews treated went on to secure more than $333 million in contracts. "Doc saved my career," says Brees, one of those QBs. "What he was able to do with my shoulder was truly amazing."
