To the LRC debate about medals in Rio, I say 3. I think Huddle & Rupp are unsuppressable talents, and will win a medal in something; not sure what, though. The third will come from either Jenny or Shannon in the 1500m. I think Jenny doubling is more likely than her switching exclusively. I would really, really, really love to say Jager will get a fourth medal, but until I see a race where he sets the fast pace (Olympics can't have pace-setters), I just can't believe that the Kenyan trio will be undone.
In the men's 1500m, the Kenyans won't allow the pace to doddle this time. It'll be fast, and it'll blow even Makhloufi out of the water, unti Makh is left fighting for 3rd with Iguider.
In the marathon, I think Eritrea will send a quiet army, and take 2 men's medals & 1 female medal. These Olympic marathons will go to countries whose people can handle both heat & humidity well at the same time. So that's Eritrea, low-elevation equitorial Africa, Brazil & other parts of Central & South America, India, and southeast Asia. Of those, only Eritrea is producing world-beating marathoners. The remaining medals, however, will include surprises.
