Defensive end Jared Allen made his presence felt Monday at Halas Hall, exuding charisma and optimism as he was formally announced by the Chicago Bears less than a week after agreeing to terms on a four-year deal with the organization.

Allen said he found a great fit within the Bears' defense and was confident that the Bears were putting things together to make a run at a Super Bowl in the near future.

On Tuesday, former Bears great Brian Urlacher applauded the signing of Allen during a visit on “Kap and Haugh” on WGWG-FM (87.7) and expressed his own optimism for what’s ahead.

Urlacher, who has gotten to know Allen some over their years competing against one another, called the gregarious defensive end “fun to watch” and “fun to be around” and surmised that he’d be a solid performer on the right side of the line after last month’s release of Julius Peppers.

“I think it’s a good signing by the Bears, especially after Pepp leaves and the problems they had getting pressure last year,” said Urlacher, now an NFL analyst for Fox Sports 1. “I think it’ll be a great acquisition for them. He’s a good guy. And he’s fun to watch too.”

With Allen’s energetic presence and big personality, there are some questions waiting to be answered as for how quickly he’ll be able to assimilate and find his niche within a defense and a Bears locker room where longtime defensive standouts Lance Briggs and Charles Tillman still have their own presence.
