Free agent defensive back Richard Marshall revealed on Twitter Tuesday night that he is en route to Miami for a facility visit with the Dolphins.

Marshall has experience at both cornerback and safety. He filled in at free safety with the Cardinals last season when Kerry Rhodes was injured, and performed admirably. Versatility is one of Marshall’s primary strengths.

The Dolphins need a third cornerback. They also need better play at free safety.

So this looks like a good fit.
