The Patriots and representatives for Rob Gronkowski are in negotiations to rework the tight end's rookie deal, according to a source. It's unclear if it's a rework or an extension, according to the source. There is no agreement yet, but the talks have been productive. Gronkowski, selected with the 42nd overall pick in the 2010 NFL Draft, was signed to a four-year contract that, with increases to 2012-14 minimum base salaries in the 2011 collective bargaining agreement, had a total value of $4.62 million.
