I think why strikers are hard to judge is that they are given massive leeway if they score.I really think if Kane hadn’t scored from the get go fans would have lost patience quickly. Kane’s all round game has come on massively. But early days he just didn’t look like a top striker but he was still scoring. So therefore a striker can contribute very little in a game but if he scores 2 will prob be Man of match. Sounds obvious to say but essentially strikers are judged on goals not their general technical ability.
