Edit: Granted, we did use the encoders for going forward a set distance in teleop. This probably would effect our accuracy in autonomous. I would imagine not by too much though. In teleop though, auto tracking would be unaffected by not having encoders.

Gyros tend to need to be level. You can cheat to an extent with some of the IMU boards doing a self leveling routine on startup and I guess that's probably a viable approach. Just don't forget it.
But why Encoders - At some point you need to get to a point on the field and that's pretty hard without encoders in the drive.
