Andrews is a 1500m guy, and could be a good one. But he has to learn some other form of tactics as well or this kind of result will be typical at the world level. Maybe he watched Borza too often (who likely has better top end speed anyway), and while it has worked for Borza at times, he has also fallen short a lot as well - his time (PR - 1.42xx) peaked a long time ago as well.
It is true that guys from the NCAA have too often relied on their kick (Sullivan and Hood come to mind) which was successful in the NCAA, but less so on the International stage. In part because some were in the El G era where fast paces developed from 800m out in the 1500m, and so they got dropped before they could even begin to kick.
I recall Brannen being touted as an 800m guy in College (he only had a PR of 1.46.00), but the reality is that he wasn't fast enough for the event at the world level and so moved up (as did Hood as well). Andrews is a bit on the bubble (much like Wheating) who likely would do better moving up, but is fine running 800's at this point in his development, as long as the preparation (base, etc.) is also being laid to move up - doing reasonably well in XC at NCAA's (Top 50 anyway) would show that he is developing the aerobic accumen to be able to move up proficiently.
Andrews often looks like he is simply struggling to keep up with the pace at 400m, and not just as a tactical ploy. That isn't a good thing, as his even pace strategy may be effective, but (like yesterday) he might simply get dropped altogether and never get back into it, or it takes a "god-inspired" effort to do so (like NCAA's), which might look impressive, but must be very draining to do on a regular basis, especially in fast races.
Symmonds isn't a really fast guy (PR - 48?) and has a relatively soft 1500m PR (3.38), but he developed in College out of the limelight (D3), and it has taken years to learn his event. So Andrews could do so as well later if he is allowed to be patient, but threads like this make one wonder if that will be the case. This will be a testament to the abilities of Vigilante to coach and develop this guy. Maybe some mentoring from Webb (and learning from his many mistakes) will be a good thing down the line for Andrews if he can keep his head and not panic about races like yesterday and learn from them instead.
