The 2013 NFL regular season is still four months away, but point spreads have already been released for nearly every single game. To be specific, Cantor Gaming released spreads for every game in the upcoming season except those in Week 17. Due to the possibility of teams resting players, there are no lines for the final week of the season, but there are for the first 16 weeks.
Here's a rundown of the 15 spreads that were released for Detroit Lions games in 2013 (team in bold is the favorite):
Week 1: Minnesota Vikings at Detroit Lions (-2.5)
Week 2: Detroit Lions at Arizona Cardinals (+2.5)
Week 3: Detroit Lions at Washington Redskins (-2.5)
Week 4: Chicago Bears at Detroit Lions (-1)
Week 5: Detroit Lions at Green Bay Packers (-4.5)
Week 6: Detroit Lions at Cleveland Browns (+1)
Week 7: Cincinnati Bengals at Detroit Lions (-1.5)
Week 8: Dallas Cowboys at Detroit Lions (-1)
Week 10: Detroit Lions at Chicago Bears (-3)
Week 11: Detroit Lions at Pittsburgh Steelers (-3.5)
Week 12: Tampa Bay Buccaneers at Detroit Lions (-3.5)
Week 13: Green Bay Packers at Detroit Lions (+1.5)
Week 14: Detroit Lions at Philadelphia Eagles (-1)
Week 15: Baltimore Ravens at Detroit Lions (Pick)
Week 16: New York Giants at Detroit Lions (-1.5)
The Lions are favored in eight of the 15 games listed above. They are the underdogs in six of the games, and one game doesn't have a favorite.
Perhaps the most interesting thing about these lines is that the Lions aren't the overwhelming favorite or the overwhelming underdog in a single game. The range for the spreads is pretty limited. The biggest line for the Lions is when they're 4.5-point underdogs at the Packers in Week 5. And the biggest line in favor of the Lions is when they're 3.5-point favorites in Week 12 against the Buccaneers.
For what it's worth, the Lions were favored in 10 games for the 2012 season at this time last year. So take these point spreads with a grain of salt considering we're so far away from the season and how much things can change once the season actually begins.
