William Byron opens NASCAR's next round of playoffs as championship favorite
William Byron returns to Las Vegas Motor Speedway as the betting favorite to win the Cup title as the round of eight of NASCAR’s playoffs opens. A win on Sunday would lock him into the title-deciding championship finale and give him the next two weeks to prepare — the same model Joey Logano used a year ago by winning at Las Vegas and then winning the title at Phoenix. Byron doesn't care what the oddsmakers say about his chances next month of hoisting his first Cup championship trophy and on Saturday wouldn't declare himself the favorite.
