Bears' O-line changes

The Chicago Bears introduced their new HC Marc Trestman at a session with the press on Thursday, and he made one thing clear: the team needs to make great improvements to the offensive line for 2013. This isn't shocking news: Jay Cutler has been sacked 113 times over the course of the past three seasons, and part of the Bears' failings can be traced to less-than-ideal play up front. To that end, Trestman has enlisted Aaron Kromer as his OC, a man who has worked directly with the Saints' offensive line in recent campaigns. But there will likely be some on-field personnel changes as well.
