In GridIron Wars, every skill position player is rated to perform as they did in real life. You'll be able to compile full statistics for every offensive player. On defense, you'll be able to track individual player stats for interceptions and sacks for most seasons where the data is available.
Defense plays a huge part in GridIron Wars, you'll "see" teams with great run defenses stuff the opposition with regularity. You'll experience the effects of team's with a great pass defense, or a lock down secondary.
