The Raiders announced that Sunday’s home opener at the Coliseum is a sellout. Did the team get a big enthusiasm boost from their unexpectedly close 21-17 loss at Indianapolis over the weekend? Sure. But the sellout (which clears the blackout rule to make Sunday’s game with Jacksonville viewable on local TV) more likely relates to something else. It’s the first football game to be played at the Coliseum since the Raiders decided to tarp off the upper section affectionately known as Mount Davis. Downsized capacity: 52,286.
