A guy way back when I was a young whippersnapper
used to teach this. Flat shoulders, high hands, lots of roll. He had a great short game, and I mean unreal great. Then all the silly boys started to say this was outdated and that you had be on plane, connected, use the big muscles, keep the hands quiet, minimise movement etc etc. All that Leady-B monkey turd ruined many a good player.
And you know what? Most of them still believe in it! Given this level of dumbness, it's no wonder the bankers and the governments can boolsheet us into believing anything. Y'all watch out now, there's a con man on every range!
