I've seen a lot of this "silver medal" theme come up in the previous chapter and I've always hated it. It doesn't matter if we're talking about Naruto or Hinata or any character, if anyone is getting into a relationship simply because they've been denied the one they really want, then they're not honest. This idea of a rebound is so hollywood highschool movie.
Even saying that Sasuke is her unobtainable dream shows the problem with SasuSaku; it's unrealistic and based off of Sakura's idealized visions of what they could be. If she can't be with Sasuke it's probably because they don't work together. I feel that when she decides to commit to Naruto, it will be because she realizes he's not some vague, far away concept but that what he has to offer is right there for her. A lot of people have fantasies of a love that never will be, but we commit and work hard for the person we want to share ourselves with and that is the true relationship.
If Sakura's reason for loving Naruto is because she's rebounding from Sasuke then it's a disservice to the character, the pairing, and the whole romance subplot. I may have had my doubts about the direction Kishimoto goes in his writing, but I'm not THAT cynical.
