Not jumping on the bandwagon (Fisher is definitely the favorite), I will say Carlos Villarreal will win. My prediction for how the race goes:
Pacer takes the lead pack through 800 in 1:58 (due to the organizers wanting someone to run sub 4), everyone slows severely the third lap trying to save energy for the kick knowing what Fisher can do. Fisher will probably try and make a break with 300 to go and attempt to do what he did last year. I see Hunter and Villarreal going with him, Hunter dies at 100 to go (similar to what happened at Footlocker) and Villarreal challenges Grant the last 100 and gets him with 10 meters to the tape.
I understand this is quite bold to try and predict the entire race but I am just trying to have some fun with this and lighten the mood on these boards with all of this doping talk going on.
