The main reason is that the motors will draw a lot of amps depending on the prop size. A higher rated ESC will handle those amp draws. A lower rated ESC will pop.
Although that motor is rated at about 80A I've measured 140A draw on mine.
The bigger the ESC the more margin you have for Amp spikes.
Cheers.
Paul.
