Stop me if you’ve heard this before: Robert Horry’s late 3-pointer … Yes, “Big Shot” Bob did it again Monday night, sealing San Antonio’s 96-89 comeback win in Denver. The Spurs can close out the best-of-seven series at home on Wednesday night. The 36-year-old Horry more than lived up to his reputation for coming through under playoff pressure on this trip to the Rockies — his swipe of an inbound pass and subsequent 3-pointer sparked the Spurs’ win in Game 3. Where does this one rank in Horry’s list of postseason money shots? “It doesn’t even make the top five or top ten,” Horry said. “There was too much time on the clock.” The Spurs haven’t blown a 3-1 lead since 1979, and the Nuggets have never overcome a 3-1 deficit.
