The Miami Dolphins are signing former New York Giants cornerback Keion Crossen, a move that can be made official sometime after the start of the new league year at 4 p.m. Eastern today. The past few days have seen a fast-and-furious “legal tampering” period, where teams and soon-to-be-free-agent players are essentially coming to terms on new contracts, though they cannot officially be executed until the start of the new league year. Who is Crossen and what are the Dolphins getting with the signing? I turned to Ed Valentine, the editor of Big Blue View, SB Nation’s New York Giants site, for a closer look at Crossen.
