Harris was known throughout the league for his physical, bump and run coverage style and was also known for his long, stringy dreadlocks, influencing others in the NFL.

Harris spent two seasons (1993–94) at Trinity Valley Community College in Athens, Texas, where he was a member of the 1994 national championship team.

He made his NFL debut a week later against the Seattle Seahawks as the starting right cornerback in place of injured Bobby Taylor.

The game was memorable for Seahawks quarterback Matt Hasselbeck's brash statement after winning the coin toss for the start of overtime, telling the microphoned referee, and thus the crowd at Lambeau Field and the national television audience, "we want the ball and we're going to score!"

In a 2004 NFC wildcard playoff game, Harris was the cornerback in primary coverage of Vikings' star wide receiver Randy Moss, who, upon catching his second touchdown of the game while being covered by Harris, famously "mooned" the crowd at Lambeau Field, an act for which Moss was fined $10,000.

Financial details of the new extension were not yet available, but Harris told the Wisconsin State Journal that it included two roster bonuses totaling $4.5 million, along with some Pro Bowl incentives.

[3] Harris played in the 2008 Pro Bowl, along with teammates Brett Favre, Chad Clifton, Donald Driver, and Aaron Kampman, as well as head coach Mike McCarthy.

[4] Harris was originally thought to be out for the remainder of the 2008 season because of a ruptured spleen suffered during the first quarter of the game against Dallas, when he collided with fellow Green Bay Packer A. J. Hawk.

On November 22, 2009, Al Harris suffered a potentially career-ending injury to the outside of his left knee in a home game against the San Francisco 49ers.

[6] Harris started the 2010 season on the 'Physically Unable to Perform (PUP)' list, then returned to practice on October 19.

Green Bay paid Harris the pro-rated portion of his $2.5 million salary, as the team was not obligated to pay the rest even though he passed through waivers.

[8] On Sunday, November 21, 2010, Harris took out a large advertisement in the Milwaukee Journal Sentinel, thanking Packer fans for 'always supporting (him)'.
