One free agent the Chicago Bears must make a priority before the start of the season

The Chicago Bears' training camp starts in about three weeks, but the team may not want to remain complacent until then.

While the Bears have one of the most improved rosters across the NFL after an active offseason, the team still has a need along both their offensive and defensive line. While the need on the defensive line will likely be addressed with a one-year signing of Yannick Ngakoue, it remains to be seen if the Bears will solidify their depth along the offensive line.

While the Bears have offensive line depth, they still have a glaring question mark at center and right guard. The plan is to start Ryan Bates at center; however, free-agent signing Coleman Shelton also received reps with the first-team offense during the team's offseason program.

Whether it's Bates or Shelton, either would be an upgrade over the center play that the Bears have had over the course of the past two seasons but neither should be viewed as legitimate answer. In addition, given the questions over Nate Davis' availability, the chance remains that Bates will slide over to the right guard spot.

If that's the case, center may still be an issue for the Bears.

The answer to that issue for the Bears should be Connor Williams.

Williams was well on his way to being the top free-agent center available this Spring before he tore his ACL in December with the Miami Dolphins. It seems a return to the Dolphins has been ruled out and Williams is likely looking for a one-year deal to re-establish himself and have an opportunity at a larger payday next offseason.

If that is the case, the Bears need to make the call as a healthy Williams would be the best center that the Bears have had in a long time. Not to mention, Williams has experience at guard and could be an option to unseat Davis as the starter.
