Robert Griffin III's mechanics are back on point after his footwork lapsed during a miserable 2013 season that ended with the Washington Redskins star quarterback's benching the final five games by fired coach Mike Shanahan.

Quarterback guru Terry Shea, who tutored Griffin prior to the 2012 scouting combine and during the run-up to the draft, spent six days recalibrating RG3's footwork and release point the last week of March in Arizona.

It isn't coincidence that without his bothersome knee brace, Griffin again looks the gifted player who took the league by 2012 offensive rookie of the year storm.

"He looked 100% healthy," Shea told USA TODAY Sports Friday. "I didn't let up on him and, boy, he kept coming — and he reminded me of the old Robert Griffin that I knew coming out of Baylor for those eight-10 weeks we worked together in 2012.

"He could have very easily lost it given the year he had. I put him through a gantlet of drills. And Robert made all the throws, showing great skills. It sure appeared to me that he took that next step as a pocket passer."

Shea, who will orchestrate Georgia quarterback Aaron Murray's April 16 pro day coming off 2013 knee surgery, worked with Griffin and nine of Redskins teammates at EXOS, formerly Athletes Performance as well as on Paradise Valley Community College's football field.

By March 29, Shea saw everything he hoped.

Griffin looked sharp and locked in throwing to receivers Pierre Garcon, Santana Moss, Andre Roberts, tight end Jordan Reed and running back Chris Thompson.

Watching Griffin take a step back during his season of struggle, Shea noticed that he was sailing some throws because he was not finishing his weight transfer on his plant leg — the one that underwent major surgery in January 2013.

Shea, who previously served as head coach at San Jose State and Rutgers as well as an offensive assistant with four different NFL teams, was surprised that Shanahan and his son, Kyle, the former Redskins offensive coordinator, had let RG3's mechanics lapse.

"For some reason, they just dropped the ball on his footwork fundamentals,'' Shea said. "I'm convinced. You get so caught up on schemes and decisions and progressions and they forget that a quarterback needs just as much attention on his footwork and fundamentals as well.''

So the Bill Walsh disciple fixed what was broken.
