Re: What is the point of "light sparring" as a consistent training method?
Nacho Beristain, use's the first round of a sparring session to just jab, no other punches just jabs. He does it with all his fighters including JMM. He uses the first round to warm up and force you to use and learn the jab.
Sparring is where you sharpen your tools and should have a purpose. A good trainer knows when you are ready to be let off the leash, sparring shouldnt be wars, there should be a plan. Like working on things and trying them in the gym sparring before you try them in a fight. I know a coach, who gives instructions to both fighters, telling them what he wants worked on. I would say that a coach who is trying to teach a new skill will go slow at first, as you get better using that skill the speed and contact will come.
