SAN FRANCISCO — Robert Kraft has done his best work as an octogenarian.
Sure, the Patriots owner, now 84, built that dynasty you may have heard of starring Tom Brady and Bill Belichick.
Sure, the Brady-Belichick years brought New England to nine Super Bowl appearances and put six Lombardi Trophies in the Foxborough, Mass., trophy case.
Sure, Kraft went from watching the Patriots from those frigid aluminum benches in the old Schaefer Stadium as a 23-year season ticket holder to purchasing the team he once rooted for as a fan to building a new stadium and a thriving business community around it.
