If the Vikings use Percy Harvin as a returner, it likely won't be a full-time assignment. Vikings sources tell Pro Football Weekly that the team would be more likely to handle Harvin on returns the same way it did Adrian Peterson as a rookie -- in a rotation, in special circumstances or late in games. That season, Peterson returned 16 kickoffs, and it wouldn't be surprising if the Vikings handle Harvin in a similar fashion. Source: Pro Football Weekly
