Although it used to be considered an anomaly, Tom Brady has almost single-handedly shifted the discussion of quarterback resiliency into an expectation of being able to play into and beyond a slinger’s 40th birthday. In many ways, it almost seems like the natural arms race that goes into any physical competition. In Track and Field, the 10-second barrier was the ultimate goal for runners until just about 30 years ago. As sports medicine improved, the physical limitations of the human body seemed to improve to make the impossible the expected.
Drew Brees, the former Charger, is also going strong well past the previous expiration date for franchise quarterbacks.
