I can say Hamilton has the biggest chance of winning as BBC SPOTY 2019. His record in the past year and in the past few months are stellar. Plus, his fan base is so huge. There are several Facebook groups about him, and his followers on Twitter are actively behind him. Add to this the fact that he's already won as BBC SPOTY before and that he's the most popular among the top 5 on the list you may not go wrong if you bet on Lewis Hamilton.
