All of the above. From what we saw on the field this year, Mike J is correct..as is the stuff about emotion, fire, etc, etc.
Check the 2nd half vs. Beefs, for instance. Their O-line was unified and blew our d-line off the scrimmage line in an almost comical manner.
Losing is not fun but is understandable at points ('cause we can't win 'em all) but getting pounded is unacceptable.
