You don't have to be.  There is plenty of material available today online
that demonstrates the futility of "religious" (meaning: dictated by dogma)
reorganizations.

None.  There is no such thing as a statement that will pinpoint
a need for a reorg.  Unless you can prove to yourself that reorganizing
any given table will improve anything in your system, then just going
through the motions because there is a "hole" is useless.
"Holes" are not necessarily the same as "disasters".

If you are using a reasonably recent version of Oracle (something you
should ALWAYS mention upfront is the version you are running),
then you can get all the information you need from the data in 
the dictionary as well as the statistics info.  

And guess what:  that is also all the information Oracle itself needs and uses 
to work around any potential problems "holes" might have caused 
in the past.

Bottom line:  only reorganize if you have a specific reason, purpose and 
target for doing so.  Just doing it because a con-sultant's SQL statement 
says so, is turning yourself into a cookie-cutter DBA.  
Which may give your boss a very warm feeling about your position, 
but achieves preciously nothing in real terms.
