I can readily accept the idea that there must be lag in the entire system and that an inline condition (where lag is lost) should only occur post-impact. That applies to golfer A as it applies to golfer B. Therefore, I cannot understand any claim that "the clubhead is harder to decelerate during impact" only applies to golfer B (and not golfer A) considering the fact that under standard conditions there is always a flat left wrist and clubhead lag at impact.

Also, how does clubhead lag at impact make the clubhead harder to decelerate during impact if clubhead speed is 100mph at the exact moment of first ball contact?
