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.
But here is part of my problem even, It worked, He helped Ryan cut weight and he looked great. Lew planned on the fighter cutting weight in the same way that had been working. JDS was just flexing his muscle there and reasserting that he was in charge. I think this whole thing boils down to both guys (JDS/Lew) havign massive ego's. JDS is no saint here he just wants to be in charge for the sake of being in charge.
