SANTA CLARA, Calif. -- Randy Moss is ready to show the world he can still be that dynamic deep threat who once dominated NFL defensive backs.

Even after a year away. Even at age 35. Even with a reputation he says isn't all it's made out to be.

Moss is getting another chance in the NFL, signing a one-year contract with the San Francisco 49ers Monday only hours after he worked out for the team and with former NFL quarterback and current coach Jim Harbaugh.

Moss' deal with San Francisco is worth $2.5 million, and he has incentives that could bring its value to more than $4 million, league sources told ESPN NFL Insider Adam Schefter.

"I'm not a free agent. I'm a guy straight off the couch, straight off the street," Moss said. "One thing I want the sports world to understand is the love and passion I have for football."

Moss will fill a big void for the reigning NFC West champions in Harbaugh's version of the West Coast offense.

While he didn't go as far as to promise not to pout when times are tough, he did say all of the right things, and that he plans to be a positive presence in a locker room known for its blue-collar, unselfish approach.

Moss has no interest in reflecting on his past, either.

This is a fresh start.

"The thing about me being here is they've done their research on me. When it comes to the worldwide sports media, I've gotten a bad rap," Moss said. "They've done their homework on me or they wouldn't have brought me in here. ... (The questions were) more of me not being a team player and things like that. I don't want to get into that."

Moss got a good vibe about the organization from the moment he was picked up at the airport Sunday night, calling it a "no-brainer" to sign.

Moss said the organization quickly decided to "pull the trigger" -- and it's a low-risk, high-reward move for San Francisco.

"Harbaugh is a young, enthusiastic coach. I love enthusiasm," Moss said. "A lot of things stood out to me."

It seems Harbaugh's throws were on target, too.

"Jim Harbaugh makes #49ers veteran emergency board: Best coach's workout in NFL history (especially while wearing khakis & a sweatshirt)," Niners CEO Jed York tweeted.
