Were refs correct in overturning Robert Griffin III's touchdown run?

With eight seconds remaining in the first half of the Washington Redskins-New York Giants game, Robert Griffin III appeared to give Washington the lead with an eight-yard touchdown scramble. The run brought back visions of RGIII in 2012: Seeing nothing ahead of him, Griffin turned on the jets and sprinted toward the end zone, finishing with a diving leap at the pylon.

It was ruled a touchdown on the field, and the Redskins were prepared to enter halftime with a 17-7 lead. After the review, however, Jeff Triplette and his crew determined that Griffin had lost control of the ball and didn't regain control before crossing the goal line. Thus, the play was deemed a fumble in the end zone and a touchback for the Giants.

Officiating pundits approved of the replay judgment, as did VP of officiating, Dean Blandino.
RG3 never repossessed the ball so this play is a touchback. It's like catching a pass.

As i said on the broadcast, RGIII needs to repossess it after the ball comes loose. It's like catching a pass.

In #WASvsNYG RG3 clearly lost control of the ball before GL. It's a fumble. To regain possession he has to hold onto it when he lands.

Griffin's teammates weren't convinced, though. Santana Moss and Pierre Garcon argued with officials, with Moss earning an ejection for his comments.
