LAS VEGAS – Derek Carr threw three touchdown passes and the Raiders gave their new fans in Las Vegas plenty to celebrate even if they weren’t allowed in the stadium by beating the New Orleans Saints 34-24 on Monday night.The new $2 billion stadium in the desert held its first event following the Raiders’ move from Oakland without any fans because of the COVID-19 pandemic.That was one of the few things that didn’t go right for the Raiders (2-0), who overcame an early 10-point deficit to the Saints (1-1) and opened the season with two straight wins for the fourth time in the past 25 seasons.Carr was in complete control for most of the night, completing 28 of 38 passes for 282 yards.
