Wariner runs 44.15, which you would think would be the fastest time of the semis, but then Merritt runs 44.12. All said 11 men under 45.
LaShawn and Jeremy look to be in a league of their own as expected (both the only runners under 44.5). But there are several guys who could probably take the bronze.
My guess:
1. Wariner 43.63
2. Merritt 43.79
3. Brown (Bah) 44.21
