The best remaining free agent cornerback is now off the board. Despite turning 30 later this year and coming off a torn Achilles' tendon, Grimes actually got one of the better contracts in this year's pathetic cornerback market. (To no one's surprise, the Dolphins paid above market value -- again.) The deal includes $3 million in guaranteed money. When healthy, Grimes is one of the league's better cover corners and is a much needed upgrade for a Dolphins secondary that ranked 27th against the pass in 2012.
