Chicago Bears signed NFL free agent Jared Allen Wednesday in a move that could well see the pass rusher transform not just the Bears defense for the better, but the whole of the organisation.
Allen had been with the Minnesota Vikings for the last six seasons after he spent the first four years of his career with the Kansas City Chiefs.
The Bears are not just signing an ordinary player with the signature of Allen, with the five-time Pro Bowler adding a high calibre aspect to the Bears defense.
Last season, the Bears were atrocious at preventing their opponent's offense from doing their damage, as Chicago's defense ranked third worst in the league, giving up almost 400 yards a game.
Even though they let go of one of their best players in Julius Peppers, the signing of defensive end Allen to directly replace him is a move in the right direction.
Add that together with other defensive line signings and the deals they've struck with several defensive backs, it's clear the Bears are rebuilding well.
For all the new names, it will be Allen that figures prominently in the minds of the opposition's they face in 2014.
The acquisition of the defensive end will allow the Bears to take their whole franchise to the next level.
This is because of the amount of quality he will bring to the table on defense, and also the amount of flexibility it will allow the Bears to have when they approach the NFL Draft in May.
Allen has 128.5 career sacks in ten seasons in the NFL and he looks to be showing no signs of slowing down at the age of 31. Only twice in his career has he failed record over ten sacks in a season, and last year made 11.5.
As well as his on field production, his actual presence will act as a boost for the Bears.
Allen plays more downs than the average defensive end, which means that they can pick more explosive players in the draft that they can develop slowly, with Allen likely to play a role in that process as well.
