Get lateral shift to create shaft lean
The speaker explains that the wider your downswing is, the more lateral shift you need, and the more lateral movement you have the more shaft lean you get. He says the reason shaft lean matters is that it makes contact more consistent and easier to hit clean shots, whereas less shaft lean makes it riskier to hit fat and thin shots and to get a strong flight.
