Source: David Andrews signs three-year contract extension with Patriots

Tom Brady's favorite center is sticking around for a while. The Patriots and David Andrews have agreed to a three-year contract extension, according to a source. The deal is worth $9 million over the life of the deal, and Andrews can earn an additional $2 million in incentives. Andrews, who went undrafted out of Georgia in 2015, would have been a restricted free agent after the 2017 season, so the early extension prevents a potential stand-off and also pays him fair-market value when the team had most of the leverage. The $3 million in average annual value would be the 14th highest among NFL centers, and that's solid money considering Andrews has been the fulltime starter for just one season.
