The Bears and Julius Peppers finalized a six-year deal to bring the top free agent in 2010 to Chicago, according to a source.

Peppers was looking for at least $12 million a year in the early part of the contract. The agreement could be worth $40 million over the first three years.

The 6-foot-7, 283-pound Peppers is a five-time Pro Bowler who recorded 10.5 sacks with two interceptions and five forced fumbles last season.

"If we bring in Julius Peppers, that could help us a lot," Bears defensive end Alex Brown said Thursday on "The Waddle & Silvy Show" on ESPN 1000. "The guy's a monster, he's an animal. He's the biggest guy and fastest guy I think I've ever seen.

"He's as gifted as [linebacker Brian] Urlacher, I think. He's just about 30 pounds heavier. He's unbelievable.

CHICAGO -- Chester Taylor agreed to a four-year, $12.5 million deal with the Chicago Bears on Friday, a league source told ESPN NFL Insider Adam Schefter.

The deal includes $7 million guaranteed in the first year, the source said.

Taylor visited Halas Hall on Friday, the first day of free agency, along with defensive end Julius Peppers.

Taylor rushed for a career-high 1,216 yards in 2006, the year before the Vikings drafted Adrian Peterson.

Taylor, who had 338 yards rushing in 2009 for Minnesota, has caught 89 passes the past two seasons, which is an important quality in a Mike Martz offense. The Bears hired Martz as the offensive coordinator during the offseason.
