John Moffitt is well aware of what he's leaving on the table.

The third-year guard, who announced this week that he's leaving the Denver Broncos, is walking away from $1 million and a shot to go deep in the playoffs with one of the NFL's best teams.

And he's fine with it.

"I just really thought about it and decided I'm not happy. I'm not happy at all," Moffitt told the Associated Press. "And I think it's really madness to risk your body, risk your well-being and risk your happiness for money. Everybody, they just don't get it and they think it's crazy. But I think what I was doing is crazy."

Moffitt started for three years at Wisconsin before the Seattle Seahawks selected him with the 75th overall pick in the 2011 NFL draft. He played in Seattle for two years before getting traded to the Broncos in August. He saw action in two games for Denver this year, and he could have earned as much as $1 million over the season and a half.

The 27-year-old Moffitt told the Associated Press that his lack of enjoyment and the dangerous nature of football contributed to his decision.

"I just want to be happy," Moffitt said. "And I find that people that have the least in life are sometimes the happiest. And I don't have the least in life. I have enough in life. And I won't sacrifice my health for that."

Moffitt called the organization earlier this week to tell the team he wouldn't be joining the Broncos after its bye week. He also took to Twitter, posting on his account for the first time since June, to announce his retirement:

As for playing in the Super Bowl, which many experts have pegged Denver to do this year, Moffitt says it was an honor that meant something to him once. But things have changed.

"I don't care about the Super Bowl. I don't," Moffitt told the Associated Press. "I used to. I mean, anytime I played this game, I gave my heart to it and I'm a person that does thing with his heart. ... I don't need the Super Bowl experience. I played in great stadiums and I played against great players. And I had that experience and it's enough."
