The Raiders began training camp over the weekend with 90 active players on the roster. On September 5th, the Raiders have to cut that number down to 53 before the beginning of the regular season. This means that competition for a roster spot will be intense across the board on a team full of unproven, untested young players, undrafted rookies, late-round draft selections and veteran journeymen.

This competition will be most intense toward the bottom of the depth chart, as players look to prove they can be capable backups and potentially significant special teams contributors. One of the key competitions going into camp will be that of the backup quarterback position. With Derek Carr seemingly firmly entrenched as the starter after an impressive rookie campaign, the question of who will sit behind him is up in the air with two contenders: new arrival Christian Ponder and third-year Raider Matt McGloin.
