As if would-be bettors didn't know already, the NFL's Week 7 opener confirmed it won't be an easy task tackling the lines out of Las Vegas.
This applies in all facets, from outright spreads to over/under numbers. Thursday Night Football made this obvious enough when the underdog Oakland Raiders took down the Kansas City Chiefs, handing one of the apparent best teams in the league a second consecutive loss and throwing the AFC wide open.
What happens next is hard to say, though oddsmakers have trotted out lines that have adjusted notably throughout the course of the week.
