The New York Giants made two expensive signings for their defensive line during the start of free agency.

Olivier Vernon agreed to a five-year, $85 million deal with the Giants. 

Vernon received the Dolphins' transition tag March 1. The one-year transition tag for a defensive end is worth $12.734 million, according to the NFL Players Association. With the tag, other teams could negotiate with Vernon, but the Dolphins had the right to match any offers.
