The San Diego Chargers and Tennessee Titans went in opposite directions in Week 2. The Chargers held off a Philadelphia Eagles comeback to pick up their first win of the season, while the Titans couldn't keep the Houston Texans from coming back, and ultimately suffered their first loss of the season when the Texans took it into overtime.
In Week 3, both teams will be looking for their second win as they face off in Tennessee. And according to OddsShark, the Titans are the team favored to net that second win. Tennessee opened as 3-point favorites, and the line hasn't moved at all on most of the prominent books around the Internet.
Given that the game is in Tennessee, one can assume that odds-makers view the teams as about even strength. Home-field advantage can often account for at least a 3-point swing, sometimes more. The over/under for the game is set at 44 points on most books. The total has gone over in five of San Diego's last six, and in four of Tennessee's last six as well.
