Quirrell's job for years."

implying that canon Quirrell is new to Hogwarts.

But, IIRC (and the Lexicon Timeline doesn't disagree), Hagrid says 
Quirrell changed after a year off.  This implies Quirrell had been 
teaching both before and after the year off, making at least 3 years 
at Hogwarts.  Of course, one of those three would have been the year 
out, so DADA would have been a substitute: who, I wonder?
