Ollie Robinson has rediscovered the formula that made Glenn McGrath one of Test cricket's most devastating bowlers. The England quick is employing an old-school rhythmical action that Australia helped revive, and it's working. Robinson's success hinges on returning to fundamentals that McGrath mastered: a repeatable, efficient run-up and delivery stride that generates pace without wasting energy. The tactic had fallen out of favor but Australia's recent emphasis on bowling technique reminded the wider cricket world of its value. Robinson's adoption of this approach shows why technique matters more than novelty. When your action is grooved and consistent, batsmen struggle to pick up length and line. McGrath proved this across two decades at Test level. Now Robinson is following the blueprint. The parallel isn't perfect, but the principle is identical. A rhythmical, repeatable action beats flashy variations every time. For England's fast bowling attack, Robinson's return to this method could provide the consistency they've lacked. If he maintains it, opposition batting lineups should prepare for real trouble.
