I get that the Bengals remain the only winless team in the NFL and that their new QB, Ryan Finley, isn't even as good as Andy Dalton. 
But the Raiders aren't a team to lay this high of a number. Only once during the Jon Gruden era have the Raiders won a game by more than eight points. Oakland is in a flat spot, too, having narrowly won a huge home division game against the Chargers last week. This is the Raiders' third home game in a row. 
Finley could prove better now that he's had a start. He's going against the league's 30th-ranked pass defense. The Raiders are down their three best players in the secondary with safety Karl Joseph out with a foot injury. Earlier they lost safety Jonathan Abram to injury and traded cornerback Gareon Conley.
It's a huge added bonus if the Bengals finally get the services of star wide receiver A.J. Green and offensive left tackle Cordy Glenn for the first time this season.  
The Bengals have been money-makers on the road covering in seven of their last nine road contests.
