INDIANAPOLIS—Chicago Bears general manager Jerry Angelo made it clear when Mike Martz was hired as offensive coordinator that he believed the roster was set for the newcomer to install his system around quarterback Jay Cutler.

The Bears are expected to shape their free agency plans around a defensive end—maybe Julius Peppers or Aaron Kampman—and a safety—any list will be topped by Antrel Rolle. But that doesn’t mean that Martz will not get a part or two.

League sources suggested that the Bears have strong interest in Brandon Manumaleuna, and the match makes sense. The veteran began his career in St. Louis playing for Martz, who has a preference for strong blocking tight ends. The San Diego Chargers are hoping to re-sign Manumaleuna, but they’ve invested heavily at the position with Antonio Gates and Manumaleuna could hit the open market later this week.

It will be interesting to see how Martz shapes the tight end position. The Bears have a savvy veteran in Desmond Clark, but he’s entering the final year of his contract and dealt with injuries last season. Former first-round draft pick is a favorite for Cutler, but doesn’t block well and may not be a fit. Kellen Davis has a great frame but remains somewhat of a project.

This much is certain: The Bears will have competition for Manumaleuna. It would be a natural fit for him to go to Baltimore where he could reunite with Cam Cameron. A source said that is another possibility. Oakland could have interest. Stay tuned.
