KJT. Torn between her and DAS, but KJT has the title of "Greatest Allround Female Athlete 2019", whereas DAS just gets "200m World Champion". Also KJT has so often fallen apart at big events, and managed to overcome her demons and put it all together at a Worlds.
On the other hand, DAS is the first ever British Sprint Female Gold Medallist.
Of the others, only Lewis Hamilton can claim to be the world's greatest. Just being the best footballer in the UK isn't good enough for me.
Where are the golfers this year? I never follow golf, but strange how they always find 1 or 2 GoaT golfers each year, who weren't in the running last year.
