Chicago Bears left tackle J’Marcus Webb is out of chances. But if he struggles against the St. Louis Rams early, either coach Lovie Smith or offensive coordinator Mike Tice will have to make the call as to whether to pull the left tackle.

That could turn out to be a difficult decision to make for the coaches because it’s not like several options currently exist on the roster.

The Bears could sub out Webb with Chris Williams, who lost out to Webb during the open competition for the starting job during training camp. Or the club could opt for Jonathan Scott, who was added on Sept. 10, and has started 28 games throughout his career at both left and right tackle with the Detroit Lions, Buffalo Bills and Pittsburgh Steelers.

The staff isn’t certain Scott is ready to make a significant contribution, considering he’s been with the team for fewer than two weeks. So if the Bears decide to make a switch at the position, it appears Williams is the most likely option to replace Webb.

Still, the Bears can’t make a knee-jerk reaction to a rough start by Webb. That could result to even worse protection at the position.
