NEW ORLEANS -- Michael Crabtree soaked up the lights, cameras and wackiness of Super Bowl Media Day on Tuesday with a smile that would have been hard to find last week.

In his first extended public comments since San Francisco prosecutors chose not to file sexual assault charges against Crabtree, the wide receiver said he was disappointed that he had to deal with the allegations but happy that he was finally able to move on.

"I don't think that can follow me," Crabtree said. "That's behind me now. I'm just really looking forward to the Super Bowl."

The San Francisco Police Department had been investigating claims that Crabtree assaulted a woman at a San Francisco hotel after the 49ers won their playoff opener on Jan. 12. The investigation was completed last week, and District Attorney George Gascon announced Friday that charges would not be filed. Crabtree, who caught six passes for 57 yards in the NFC Championship, said he never considered the investigation a distraction.

"I respect the system and whatever they had to do," he said. "I was disappointed with the allegations, but at the same time I had to deal with it."

The Ravens will have to deal with Crabtree on Sunday, and he said he still feels that he has something left to prove despite having the best season of his career. Crabtree led the 49ers with 85 receptions, 1,105 yards and nine touchdowns, and on Tuesday he credited Randy Moss with much of this season's growth.

"A guy like that, a legend, is someone that you looked up to when you were younger," Crabtree said. "He plays a big role. His voice alone gets you hyped. Him being around just brings the best out of us."

Crabtree compared Moss to Charles Barkley in terms of being somebody who isn't afraid to speak his mind, and said the receivers have even coined a phrase during their first season with Moss.

"When you catch a ball over (a defensive back), it's always 'getting Moss'd,' " Crabtree said. "Its funny -- you talk to the DB and you say 'You got Moss'd' and Moss is sitting right there next to you."

While Moss sat a few podiums down at the Superdome and called himself the greatest receiver of all time, Crabtree shied away from any bold proclamations. He plans on keeping a low profile and called the experience "unreal." But he doesn't plan to call his shot.

As he sat on a podium stationed in the corner of the 49ers end zone, Crabtree said he isn't holding on to any lifelong dreams of catching a game-winning touchdown in the Super Bowl. He doesn't want the 49ers to even be in that position.

"I dream of having the game over at halftime," Crabtree said, smiling.
