With so many front runners in the 800 going to nationals breaking 146 already, I don't think Wheating will need to worry about pushing the pace himself until at least the last 200 m. It's then that he needs to put distance between himself and the rest of the field, including Andrews. The question is whether Andrews will be too far back at that point to have a chance of reeling him in. We all saw Wheating make the same mistake at NCAAs two years ago when he let Hernandez get a little too far away. If Andrews lets Wheating get that far ahead, he has no chance given Wheatings kick.
And for those that claim Andrews has more raw speed than Wheating, I'd say the evidence so far is inconclusive. Both times Andrews has edged Wheating, Wheating has been doubling and looked less than his usual self. And for anyone who thinks he's incapable of putting on a burst of speed like Andrews, look no further than 2008 NCAAs, when he made up almost 5 meters on Hernadez in the last 25 m
The bottom line is, we haven't seen Wheating at his best against Andrews. With only one race a day at Nationals, he should be ready to give it his all. If conditions and pacing are good, I predict the winning time will be <1:45.
