The complete NFL schedule for the 2015 season was released on Tuesday night, and Las Vegas got to work by immediately putting out early lines for Week 1 games.

The biggest favorite in the opening week is defending Super Bowl champion New England. The Patriots are favored by six points over visiting Pittsburgh.

Seattle, New England's opponent in the Super Bowl, opens as an early 3.5-point favorite on the road against the St. Louis Rams.

The Tampa Bay Bucs have the No. 1 pick in the upcoming NFL draft, and they are set to face the Tennessee Titans - who pick second - in the season opener for both teams. Could it be a Jameis Winston-Marcus Mariota matchup?

The Bucs are 3-point favorites over the visiting Titans right now.
