Interesting question, my first reaction was yes, but I would have thought she would have been announced on the Gophersports website by now. I now suspect that they are waiting for academics to qualify her or the rumored fight in a game or some other reason caused the gophers or Deja to back off the commitment.
Well there is a clip of her dunking. she approached the rim and someone threw the ball up in front of it as she jumped and she two handed dunked. It's not like you're going to see her throw down in a game but still impressive.
