Matt Schaub will not need to win a quarterback competition in Oakland to become the Raiders’ starting quarterback. He already is the Raiders’ starting quarterback. Raiders coach Dennis Allen said after Schaub arrived in a trade with the Texans that Schaub will open the season as the No. 1 quarterback. “We brought Matt Schaub in to be our starting quarterback,” Allen said. “We feel very confident that he is going to be able to come in and function in that role and be outstanding for us. Obviously, we love having competition within the team, but right now Matt Schaub is our starting quarterback.” The Raiders also have Terrelle Pryor, Matt McGloin and Trent Edwards on the roster, and they could draft a quarterback like Teddy Bridgewater, Blake Bortles, Johnny Manziel or Derek Carr. But Allen, who was an assistant coach in Atlanta when the Falcons drafted Schaub in 2004, says Schaub is his guy.
