UNH/DEL as 2/3 preseason CAA poll was too high IMHO. There is a large quality dropoff after JMU and any one of five or six teams could have been be ranked right behind JMU (including SBU, Villanova, Elon, etc.) in the CAA.
So, these were CAA upsets, but not huge CAA upsets IMHO. (URI or Maine beating JMU would be a huge upset)
Last year URI opened up like gangbusters, taking FCS Central Michigan to the wire before losing in overtime. And Delaware is no Central Michigan. And last year UNH was mysteriously obliterated by a weak Holy Cross (Patriot League) team 51-26 so losing badly to Maine is not entirely unprecedented.
