I think one reason so many games are totally uninteresting is the search for the Elite QB
More younger QB's are playing based on
a) the QB salary structure and
b) the need to find an Elite QB
Teams can not afford to let a rookie QB sit on the bench for a year or two until they are ready so we have the pleasure of watching not-ready-for-prime-time QB's such as Ridder, Howell, Young, Richardson, Pickett, Fields, ...
They may turn into great QB's, but they are not very watchable as of now
