They are so easily impressed.  Their deep in-depth "sniffing" involves going to the Port of Long Beach's website and pulling statistics out.  That's some rock-solid Will Pitt level journalism.  From the site (

So the net impact on cargo for loaded containers is 5,120,015 (est) TEU's this year versus 5,213,640 last year.  A change of less than 2% that indicates that our trade imbalance may be shifting to a more favorable position.  Can't believe that the sky isn't falling on that.
FYI, since it's rather obscure, a TEU is a 20 foot equivalent unit.  It's a "unit" to measure containership cargo capacity with a standard TEU being a twenty foot ISO container.
