I agree that expected poor field conditions could be a safety concern. But you never used to see games moved due to expected "normal" weather conditions like rain, snow or wind. I guess I am just getting old and grumpier.
Speaking of the Refs, Refs at the WB/Friends game were by and large much younger than what I have been seeing in NCCo and the game was officiated pretty well comparatively. Based upon what I have been seeing, games that appear to be more poorly officiated seem to involve some of the older officials who have trouble getting up and down the field.
