Despite pain, Niners play it back for closure, fuel

-- In the days after their loss in Super Bowl LIV, the San Francisco 49ers haven't shied away from reliving the disappointment.The Niners have already watched the 31-20 loss to the Kansas City Chiefs again, some even for repeat viewings."I've watched the Super Bowl at least five, six times," receiver Emmanuel Sanders said Wednesday. Defensive tackle DeForest Buckner said he watched the game and took notes on what he needs to do to make the "plays that I feel like I could have made that I missed."At the top of that list was the third-and-15 pass by Chiefs quarterback Patrick Mahomes to receiver Tyreek Hill for a gain of 44 yards, which set up Kansas City's 21-point scoring spree with about seven minutes to go.On the play, Buckner narrowly missed dropping Mahomes for a sack that likely would have forced Kansas City to punt and could have helped put the game away."That was probably the biggest play of the game," Buckner said. They told the players to be proud of this season and to file away the feeling they had walking off the field at Hard Rock Stadium.In a viral video making the rounds on social media Wednesday, tight end George Kittle can be seen vowing to return to the Super Bowl with "a m-----f---ing vengeance" in the game's closing moments."If it doesn't automatically turn into fuel for you, then I think you're in the wrong sport," Kittle said.Of course, before the 49ers can turn the page to returning to the game's biggest stage, they will have to go through an offseason sure to bring plenty of change.Sanders, defensive lineman Arik Armstead and free safety Jimmie Ward are all set to become unrestricted free agents in the next six weeks.
