What does CAR mean in football statistics?

CarAV - career approximate value. See the entry on AV. The Career AV is computed by summing 100% of the player's best-season AV, 95% of his second-best-season AV, 90% of his third best, and so on. The idea is that the Career AV rating should weight peak seasons slightly more than "compiler"-type seasons
