Robert Griffin III (RG3) might be ahead of schedule on a return for the 2013 NFL season from an ACL and PCL injury suffered during the playoffs.

"I've been real mum on talking too much about RG 3," world renowned surgeon Dr. James Andrews recently told ESPN while working on a feature about South Carolina running back Marcus Lattimore, who is also under Andrews' care. "He wants his recovery to be fairly private, but I can tell you he's way ahead of schedule. His recovery has been unbelievable so far. RG3 is one of those 'superhumans.' First patient I ever had like that was Bo Jackson. And recently I, of course, had Adrian Peterson, who is also superhuman. They have an unbelievable ability to recover; where as a normal human being may not be able to recover."

Adrian Peterson returned from an ACL and MCL injury in 2012, then won the NFL Most Valuable Player award after rushing for 2,097 yards in the same season. He returned in eight months from injuries that at the very least, takes a year to recover from before even practicing. This set a measuring stick for others to hope to follow.

Griffin injured his ACL and posterior cruciate ligament when his Washington Red Skins were winning a playoff game against the Seattle Seahawks. The NFL Rookie of the Year was eventually forced to come out of the game that turned into a 24-14 loss.

An ACL is the anterior cruciate ligament, which is a part of the knee. The ACL and the the medial collateral ligament (MCL) are two of the four major ligaments of the knee.

 Healthy knees are important for a running back to make cuts and for quarterbacks to plant in the pocket, before throwing a pass down field. For Griffin, his knees might mean everything.

Griffin ran for an all-time 815 rushing yards last season.
