Final prediction:
1.Hocker: looked horrifically comfortable in the heat, despite its being much faster than the other one, will run on pure hate. Assuming he's in shape tomorrow (big if), he should have the best kick for anything above 13:10. Would still be a great threat in the range of 13:00-13:10. Not sure how he holds up in sub-13, but overall wouldn't be surprised to see him shock the world once again since Paris.
2.Gressier: looked comically comfortable in the heat, has a great kick and is seemingly in great shape. Will he pull off the double golds since Mo in Rio? We must wait see and see.
3.Mills: looked solid, the PBs (3:28, 12;46) suggest he would be a factor, be it fast or slow, While hardware is lacking. he did look solid in the heat, maybe a dark horse?
That said, it's pretty much an open race, so 99.9999999% I would be wrong. lol
Edit: Ah, originally I had Young for Bronze, but he looked terrible in the heat, though look could be deceiving, like Laros looked the best in the semi, but we know what happened in the final.
