Remember a few months ago when Dolphins center Mike Pouncey and his twin brother wore “free Hernandez” hats in support of their former college teammate, Ex-Patriot and accused murderer, Aaron Hernandez? Well now, Pouncey has an opportunity to put that support in action. The center was served on Sunday by Massachusetts State Police with a grand jury subpoena, less than an hour after the Patriots defeated the Dolphins 27-17 at Gillette Stadium.
