Where in the world is free agent Vontae Davis? On Friday, the cornerback continued his travels by visiting with the Dolphins in Miami, according to a source who spoke with ESPN.com’s Adam Schefter (on Twitter). In the last week or so, Davis has met with the 49ers, Browns, Bills, and Raiders. He hopes to sign with a team before free agency opens on March 14, but not before doing his homework on several interested clubs. Davis is in a unique position as an accomplished veteran who is free to sign with teams before most are eligible for the open market.
