Inconsistencies in the DADA position

I always have Snape on the brain.....


"You have applied regularly for the Defense Agains the Dark Arts 
post since you first joined the school, I believe" 
   - Umbridge, to Snape, pg 364 OOtP, US ed

"the Ministry has the right to appoint a suitable [teacher] if - and 
only if - the headmaster is unable to find one."  
   - Dumbledore, to Umbridge, pg 597 OOtP, US ed


"He was the on'y man for th job....An' I mean the on'y one.  Gettin' 
very difficult ter find anyone fer the Dark Arts job.  People aren't 
too keen to take it on, see.  They're startin' ter think it's 
jinxed."
   - Hagrid, about Lockhart, to HRH, CoS 115, US ed  


So these three things do not add up.  Taking quotes one and two 
together, it would seem that DD is specifically keeping Snape from 
the DADA position.  But quotes one and three directly contradict one 
another.  In addition, if we assume that Snape was telling the truth 
about applying every year but Hagrid was wrong in quote three, what 
would make DD think that Lockhart would be a more suitable candidate 
than Snape?  I know characters will sometimes give misleading 
information, but something about this really bugs me and I can't put 
my finger on what it is.  Any thoughts?
