“Harry Kane is Broken” fever is sweeping the soccer Twitter world. And that was before Harry Kane actually limped off the pitch against Southampton on Wednesday with an apparent hamstring injury. Nearly a year ago, Ted Knutson first mentioned on the StatsBomb podcast that Kane might be Fernando Torres-ing. I was resistant. I thought some time off this summer, time he did not have in 2018, would finally give him some rest and let his ankles heal, helping him to regain the
proprioception that allowed him to Moneyball his way to becoming a shot monster despite his relatively limited athleticism.
That’s certainly not happened. He’s declined markedly in terms of shot generation and has not made up for it by improving elsewhere. However, Kane has managed to maintain his elite finishing ability. Over his career, he has outperformed his non-penalty expected goals by around 20%. When he kicks the ball, he still hits it hard and to the right places.
The problem is that he does not shoot anymore. When Nabil Bentaleb and Ryan Mason were Spurs’ midfield in 2014–15, Harry Kane took 4 shots per match. At his best, in 2017–18 (before the ankle injury that truly derailed his career), he took nearly 6 shots per 90 minutes. Now, Harry Kane attempts under three shots per 90, and his xG per shot has decreased. His non-penalty xG per 90 is a paltry 0.3. Relatedly, in 2017–18 Tottenham had 1.8 xG per match but have dipped to 1.3 xG per match, even as Son Heung-Min remains excellent. It’s bad, folks.
