It depends on what you've chosen to use the gyro for.
As a simple assist in driving straight you can use the momentary values coming from the gyro and ignore extreme values generated by it on turns or during collisions.

Using it to command turns in autonomous or with field centric driver controls won't work if you saturate the gyro. It won't know where it is.
Robot-to-robot hits can over saturated the gyro, as well as, quick turns.
