Richard Sherman was voted as the cover athlete for Madden NFL 15 and he's now attempting to have Earl Thomas, Kam Chancellor and Byron Maxwell join him.

The secondary is famously nicknamed the "Legion of Boom."

"I've been trying to get the Legion of Boom on the cover, and EA has been fighting me," Sherman told reporters Monday at the Seahawks' OTA. "So if everybody wants to start a petition to get the Legion of Boom on the cover, here it is, here's an open invitation."

Sherman is only the third defensive player to make the Madden cover.

Sherman reiterated his appreciation for the cover vote Monday, referring to it as an honor.

"It was cool. It was really cool," Sherman said. "It was a great experience. It's always an honor being picked for 'Madden.' It's a fun deal."
