Olympics are most important for me so there is small number of summer athletes. I also add some categories of my own (or heywoodu )
Male sportsman of the year: no idea - there was no one who made more impression on me than other atheletes, but if I had to choose I would say Alejandro Valverde or Shaun White, but that's only because of my preferences
Female sportsman of the year: Ester Ledecka
Team of the year: Sweden men's biathlon relay and Hungary men's short track relay
Greatest moment of the year: semifinal of volleyball men's WCh Poland vs United States
Biggest suprise of the year: David Gleirscher
Biggest idiot of the year: FIS jury in olympic ski jumping normal hill competition
Biggest disappointment of the year: no medal for Sven Kramer on olympic 10k and no medal for Felix Loch in olympic luge singles
I would like to mention about German men's ice hockey national team also. Unfortunately they lost in olympic final so they can't be in one of above categories, but they surely are worth mentioning.
I wouldn't be myself if not mention about Polish athletes and because they weren't in "world" categories there have to be "Polish" set of them
Polish male sportsman of the year: Kamil Stoch - two olympic medals, World Cup, 4-hills tournament, Raw Air...
Polish female sportsman of the year: Agnieszka Kobus-Zawojska, Marta Wieliczko, Maria Springwald, Katarzyna Zillmann - quadruple sculls world champions
Polish team of the year: men's volleyball national team - world champions second time in a row
Polish greatest moment of the year: that's hard but I would say Kamil Stoch's gold at large hill in Pyeongchang but only because: olympics > WCh
Polish biggest suprise of the year: Dorota Banaszczyk winning gold medal at karate WCh in kumite 55kg
Polish biggest idiot of the year: Leszek Krowicki - coach of Polish women's handball national team
Polish biggest disappointment of the year: 2nd round of olympic ski jumping normal hill competition
In the end, I know that this topic may not be place for discution, but I have to ask:
But why? Why fact that after four runs they both had exactly the same time is disappointing? I think it was the best two-man competition since SLC.
