We're entering the second quarter of the 2018 NFL season, which presents a fine opportunity to reflect on what's been an historically unpredictable campaign to date.
Only 46 percent of Las Vegas favorites have covered (compared to 52 percent in 2017), and only 63 percent of favorites have won outright (compared to 70 percent in 2017). Meanwhile, more than 60 percent of games have been decided by one score (up from 47 percent in 2017), and only 16 percent of games have been decided by three or more scores (down from 27 percent in 2017).
