Dr. James Andrews, a renowned surgeon who operated on Redskins quarterback Robert Griffin III, called his ability and motivation to come back from knee surgery "superhuman," according to NFL.com. Griffin III was the second overall pick in last year's NFL Draft and tore his anterior cruciate ligament and lateral cruciate ligament in the wildcard round of the playoffs last season.

In the report, Andrews compared Griffin to Minnesota Vikings running back Adrian Peterson and former two-sport icon Bo Jackson and said "conventional recovery timetables don't apply" to them.

Griffin III crumpled to the ground in the fourth quarter of a 24-14 playoff loss to the Seahawks and fellow rookie quarterback Russell Wilson with a knee injury that many felt could have been avoided. Griffin III had tweaked that knee in a December game against the Baltimore Ravens and clearly aggravated it in the first quarter of the Seahawks game. He insisted that he stay and in the game and head coach Mike Shanahan obliged; the injury sapped Griffin III of his effectiveness though, and eventually the joint just gave out.

Mike Shanahan told NFL.com's Kimberly Jones that his signal-caller is ahead of schedule in his recovery, backing up Andrews' claims. Griffin III's teammate, tight end Fred Davis also spoke glowingly of RGIII's comeback campaign.

On Friday's NFL AM Davis said, "You can barely even tell that he's hurt. He's doing every drill. He looks comfortable and normal to me. When he first got back, I was surprised, like, 'Did you just have surgery?'"

Griffin III won the 2012 Rookie of the Year award over Andrew Luck, who was selected first overall by the Indianapolis Colts in the draft, and Russell Wilson who beat him in the playoffs. For the year, he threw for 3,200 yards and 20 touchdowns while only tossing five interceptions. He was an equal threat on the ground, using his track and field speed to torch opposing defenses for 815 yards and seven more scores.
