The New England Patriots are not waiting for an offensive line problem to become an emergency. Van Roten is 36 years old, has played for six NFL teams and is not going to be sold as a long-term building block. The Patriots have not signed Van Roten, but the visit comes as they continue evaluating their depth at guard during training camp. Free agent OG Greg Van Roten is visiting the New England Patriots today, per source. They do show he remains capable of handling meaningful snaps if injuries force the Patriots to shuffle their offensive line.
