Rob Gronkowski (2014)
Gronk’s first appearance on this list relates to his ACL injury in 2014. He is one of the greatest tight ends ever but faced adversity with many injuries throughout his career. Tom Brady also had an ACL tear but never had speed to lose. Yet tight ends depend on their speed, mobility, and agility over the middle of the field, so many people feared for Gronk’s career.

In the end, they didn’t have anything to worry about because he stormed back in style. Gronkowski won two more Super Bowl rings with the Patriots and another with Tampa Bay. He didn’t slow down at all and proved that modern sports science is in a different realm from the olden days (via ESPN).
