We have chosen the number nine shirt in recognition of the fact that prostate cancer affects one in nine men. And it could be one in eight or even seven by the end of the season.
Beyond that, there's no shirt more iconic than the number nine. In footballing days of old, every shirt number had meaning: Number three was traditionally the left-back, number seven the tricky winger, and so on.
In today's world of large squads - where it's not uncommon to see a player take to the field with a 36 on their back - numbers have less significance. Except, that is, for the number nine shirt.
When squad numbers are assigned before the start of a season, there's an expectation levelled at the number nine. This is the guy that's going to score the goals to lead your club to glory - or at least to safety from relegation. He's your talisman, your hero, your saviour. Well, that's the theory, anyway.
Thanks to our 72 bloggers, we've got a definitive list of each Football League club's most cherished number nines - 360 strikers who have scored their way into fans' hearts.
And just to prove that sometimes the weight of responsibility is too much to bear, our bloggers have also selected a number nine who stood out from the crowd - but for all the wrong reasons.
Each week, Adrian summarises the best number nines of the weekend, too.
