Adrian Peterson -- I'm a Super Dad

Adrian Peterson wants everyone to know he's a super dad ... so he dropped a picture of himself online Saturday that can be summed up with one word -- REALLY?!

Peterson tweeted a pic behind a cardboard cutout of "Super Dad" ... with his head in the empty hole -- alongside his young daughter.

The caption read, "My beautiful daughter A'deja. Dad's & Donuts Day. #LOVE "

Now we know it's a nice gesture ... but with his history of child abuse -- see here and here -- is it really a wise decision to tout yourself as "Super Dad" online?!
