ESPN will announce later today that four key members of the network's NFL coverage -- John Clayton, Mel Kiper Jr., Adam Schefter and Ed Werder -- have signed multi-year extensions with the company. For those who enjoy Kiper Jr. on the NFL Draft, the following will be good news: Kiper Jr. signed a six-year deal that will keep him at ESPN through the summer of 2018. Schefter signed a five-year extension that runs through the summer of 2017. Clayton and Werder each signed four-year extensions. Why did ESPN lock up this quartet of NFL talent? "The NFL is 12 months a year and our fans cannot get enough news and information," said Mark Gross, an ESPN senior vice president and executive producer. Source: ESPN.com
