Big ups to Luckie815 for this one.
The biggest shocker for the Bears this offseason is the news that Bears RT John Tait plans to retire. The article can be read here. With Tait gone, the Bears must almost certainly sign John St. Clair and draft a lineman. It will also free up some cap room heading into free agency.
UPDATE: It is being reported that Tait is expected, not considering retirement. If he did, it would give the Bears an additional 5 million of cap space.
