Someone wrote in their predictions that Tonks would be the next DADA 
teacher, but in disguise.  This could work because it would seem to 
follow the pattern of the DADA teacher being a new character (since 
Harry wouldn't be told that it's Tonks), and her clumsiness would be 
the clue that it was her all along.
It would work out because she's an auror and would be useful at 
Hogwarts.  Not sure if I completely buy it, but it could be the way 
that her ability could be used by JKR.
