NFL rosters see lots of movement

Brett Favre's retirement naturally overshadowed a bunch of other moves in the NFL on Tuesday, including one of his nemeses leaving the game.

The iconic Green Bay quarterback's decision to stop playing after 17 seasons, an unprecedented three MVP awards and a slew of passing records sent the official retirement of Warren Sapp to the back burner.

Sapp's 13-year NFL career officially ended when his retirement was posted on the Oakland Raiders' Web site. Sapp said immediately after last season that he was through playing, but did not file the paper work. The posting on the team's site was the first official word that the star defensive tackle was done.

In January, the 35-year-old Sapp posted a two-word message on his Web site: "I'M DONE!" He had told teammates and coaches his plans after the season finale against San Diego.

Sapp made seven Pro Bowls, won the 1999 Associated Press Defensive Player of the Year award, and led Tampa Bay's dominant defense that won the Super Bowl after the 2002 season. He finished his career with 96 1/2 sacks, 28th overall since the NFL began keeping track of the statistic in 1982, but extra impressive because he played tackle.

Sapp spent nine seasons in Tampa before joining the Raiders in 2004 as a free agent. He mostly struggled with the Raiders, except for a strong 2006 in which he had 10 sacks, and had become more of a situational player in his final season.

In 2007, he had only two sacks and the Raiders' defense struggled against the run, allowing a league-worst 4.8 yards per carry.

His running "feud" with Favre brought some levity to a sometimes brutal game. Sapp was known as a trash talker, and Favre often went directly back at him with a smile when both the Bucs and Packers were in the same division and played twice a season.

One day after re-signing star receiver Randy Moss, the Patriots addressed needs at cornerback. With CBs Asante Samuel and Randall Gay gone as free agents, New England signed Jason Webster.

Webster has 393 tackles and 11 interceptions in 87 career games, 74 of them starts. He played in one game last season for Buffalo before injuring his arm.

The eight-year veteran was a second-round draft pick of San Francisco in 2000 and played four years with the 49ers before signing as a free agent with Atlanta, where he played for three years.

Patriots coach Bill Belichick said Webster is "an experienced veteran who will add good depth to our secondary."
