Penko the tailwind at 270/11 was 5 knots (10 cross). Hand flying on short final I would see no reason to break off the approach in a 737 to a long runway with that reported wind. In many years as a captain on the 737 I favored having the FMC page open with the wind component but again for the reasons given in the excellent post above you treat it with caution particularly with regard to gusts. The problem came when they did not react to the rapidly changing reported wind and crucially in not going around when they missed the touchdown zone.
