JDS is a fighter not a coach, how much hands on experience do you think he has with fighters cutting weight? Its not meant as disrespectful to JDS but obviously somebody who has a history of actually cutting weight themselves is gonna be a little more knowledgeable especially considering Lew also comes from a very respected gym and one with a considerable amount of wrestling pedigree. Team Quest has a lot of experience I am sure with weight cutting. If I was the guy cutting weight I would rather have Lew to help me than JDS.
Lew went to the house and planned on having one of JDS' fighters cut weight using a method JDS had already said he didn't agree with using any more. JDS has more than enough knowledge on the subject to intelligently prefer one method over another.
