In theory, there is no difference between theory and practice. In practice, however...

Mecanum wheels' rollers do spin when driving in a straight line on carpet. This robs them of forward speed. Perhaps on a rigid surface like tile or concrete the "just like a traction wheel" model is adequate, but it falls short on a typical FRC field.
