Athletics- 3-5 (men's javelin, Spotakova, Hejnova, possibly Maslak or Drahotova, others possible but unlikely)
Badminton- not going to happen
Canoe Slalom- 2-3 (Kudejova, Prskavec, probably one other)
Canoe Sprint- 2-3 (Fuksa, 4-kayak, possibly 2-canoe)
Cycling- not going to happen, road or track
Mountain Biking- 1 (Kulhavy, would be nice to see Nash but probably not)
Fencing- very unlikely Choupentich can pull it off
Gymnastics- not going to happen
Judo- 1 (Krpalek, others unlikely)
Modern pentathlon- 1-2 (Svoboda, Kuf maybe)
Rowing- 1-2 (Synek, Knapkova)
Sailing- very unlikely (Fenclova is good but I don't think she will medal)
Shooting- 0-2 (Kostelecky/Sykorova/Mazurova could pull it off, but I honestly think even one medal would be an achievement)
Swimming- very unlikely, synchronized also
Table tennis- not going to happen
Tennis- 1-2 (Hlavackova/Hradecka, possibly Kvitova or other doubles pair)
Triathlon/Volleyball/Wrestling/Weightlifting- not going to happen.
It's a pretty optimistic list, I guess.
