The common factor is that they are on the ground, they have been overpowered and they are afraid for their life. In this instance, if you can reach a knife on your person and bring it to play how much training does a person need to attempt to save their own life?

My answer is little or none. There is nothing wrong with training provided it has a practical application and it's taught by a qualified instructor. I'm just saying that i believe my scenario, or a variation of, is more likely to present itself than some sort of "knife fight".
