When this fine Friday of Week 15 started, Minnesota Vikings running back Adrian Peterson was owned in a tad more than half of ESPN’s standard leagues and, at least to the general public, had little likelihood of changing it this week. After all, Peterson had suffered a torn lateral meniscus in his right knee back in Week 2 and while he boasted he’d return before the end of the season, it didn’t seem so likely. Well, news broke Friday afternoon that Peterson intends to play Sunday against the Indianapolis Colts, so the story has clearly changed.
