An aggressive first weeks of free agency by the Bears has created a situation in which “needs” have become “wants” -- as in the Bears “needed” a linebacker or two without Nick Roach and Brian Urlacher, vs. “wanting” a linebacker or two after the signings of James Anderson and D.J. Williams. The Bears don’t “need” a left tackle after Jermon Bushrod, or “need” a tight end with Martellus Bennett in place. They “want” a pure speed receiver for the outside (who doesn’t?) and they “want” another receiving tight end. But their game-day lineups are largely set with veterans already. But they have not dialed down every “need” to a “want.” Guard Signing former New York Jet Matt Slauson secures one guard spot, probably left guard, which he played primarily with the Jets. The Bears have a gaping chasm of unknown at the other guard. Gabe Carimi is getting a look at guard because he didn’t work at tackle, or at least hasn’t yet. Edwin Williams is a valued inside swing man who had the left guard spot for two starts but then lost it to James Brown, an undrafted free agent and the fourth installment at the position.
