WD, first, my answer is no.
I think that most coaches/athletes (or on "main street") that have had some degree of success all think they can get the job done. They may be wrong but most competitive people feel they can still do the job....only natural imo.
CMR probably feels he can still do the job....heck CTG probably thinks he can as well.
Would venture to say that everyone on this forum believes they can get their jobs done better than anyone else.....
