Buoyant Warriors fans hang onto their optimism after Game 4

San Francisco's a baseball and football town, but for three hours Monday night, basketball was the only game that mattered.In pubs and coffeehouses, sports bars and sit-down restaurants, just about every public television in the city — and across the rest of the Bay Area — was tuned in to the Warriors' attempt to clinch a spot in the NBA finals for the first time in 40 years.The Warriors failed to grab their fourth win in the Western Conference finals Monday.[...] the only outcome that really mattered was the status of NBA MVP Stephen Curry, who left the game in the second quarter after hitting his head in a scary tumble."Hitting his head and spine, and his arm folded under him — that wasn't good," said Bryan Lawrence, 34, who followed the game with his dad and a friend at the Chieftain south of Market Street.About the Warriors' chances of winning the series and heading to the NBA finals, Lawrence said he wasn't worried.[...] we have something to cheer about.Besides the Giants.[...] many longtime fans said they feel like their team is finally getting the same star treatment granted to the Giants and the 49ers, especially in recent years.
