Pats extend top personnel exec Caserio … New England will reportedly retain Nick Caserio as the team’s director of player personnel. There had been an expectation that Caserio might become Houston’s G.M. once his contract with the Patriots expired after the Texans tried to hire him away from the Patriots last year. That resulted in the Patriots accusing the Texans of tampering, and in the end Houston backed off. And any talk of Caserio leaving for Houston when his contract expired this year became moot when the Texans named head coach Bill O’Brien the new G.M. along with his coaching duties.
