The two most impactful quarterbacks of 2017 both ended their seasons on the sidelines with torn ACLs. Deshaun Watson and Carson Wentz put together highlight-reel campaigns before being struck down with knee injuries.
Watson's injury came in practice after six starts, while Wentz's season ended as he was attempting to scramble for a touchdown against the Rams in December. Their injuries were not the same -- Watson's was strictly an ACL tear, while Wentz also tore his LCL and had damage to his IT band -- but the stories are similar enough: Young quarterback emerges as a superstar only to suffer a serious knee injury.
