Wasn't it dumb that the NFL postponed the Seahawks game Sunday because of lightning - the arches in the Stadium act as lightning rods!

First, the arches at Century Link are an architectural and structural feature-they are NOT lightning rods. Second, lightning rods don't guarantee safety within a zone; they attempt to capture and channel lightning strikes to 'ground' to minimize the potential of fire and building damage.

Given the forked/multiple nature of lightning, an arch or two (even a lightning rod or two) hardly produces a 'safe zone' from lightning. Such a stadium also does not act as a 'Faraday cage' (similar to a car) in protecting occupants.

The NFL and Seahawks acted on the advice of the National Weather Service meteorologists on duty and made the only correct and responsible choice. So did all the fans who followed that direction.

This question (based on a radio talk show host's opining on the air) unfortunately is an example that the ability to express an opinion does not guarantee it actually has any basis in fact.
