I believe this article makes great sense in explaining how you must question yourself on your own accountability.  I especially liked the parts about policing yourself and looking at yourself first.  By playing football, I have witnessed many of times of teammates not taking accountability for themselves.  For example, the d-line blaming the defensive backs on getting beat on a long pass.  Maybe if the pass rush would have been more effective, the quarterback and receivers wouldn't have had that time to connect.  You must look at yourself and ask:  How can I improve to make the problem better?  Do not point the finger at someone else.
