We've seen wheelspin when accelerating quickly, and the wheels will slip when the robot gets hit hard. Both of those are relatively common in a match, so the encoders will no longer be at the correct position. This doesn't mean that encoders are useless sensors, but that they aren't a magic bullet. A clever algorithm would decide which one is more likely to be right, and use it to correct the other one based on the measured conditions.
