It will be interesting. What made shawn such a great gymnast was how easily she could do the hardest skills being done on every single event, she didn't code-whore.
I think this comeback will turn Shawn into the opposite gymnast that she was, she'll probably have a more fluid sense of movement and more maturity and line, but she will code-whore to the max to get her difficulty. I can't see her ever doing a 2 1/2 Yurchenko or double double on floor again, but we'll see. The problem with Shawn making the team is her strong events are already covered, and bars is the biggest hole to fill, which is why Nastia IMO would have an easier time coming back.
