"I always had faith that I'd be a Miami Dolphin for life," an emotional Pouncey said, per the Miami Herald. "(It's) truly a blessing to be here."
"I look back at my career and could have done so (many) things better. ... What I put my family through."
Pouncey acknowledged the Dolphins could have cut ties with him over past incidences and regrets his actions.
Pouncey added there is a "there's a right and wrong way to do stuff" and said it takes more than ability to earn the new contract he's signed.
The Dolphins also confirmed that Pouncey would return to playing center after spending last year at guard.
"I can't wait," he said of moving back to the pivot. "I feel like I'm one of the top centers in the league when I'm playing at the top of my game."
