The LVH SuperBook in Las Vegas recently released updated NFL odds for the 2013 season. There are odds for win totals, division champions, the Super Bowl champion and which teams will play in the Super Bowl, and National Football Post has a rundown on all of them.
For the Detroit Lions, their over/under for wins in 2013 is set at 7.5. The over is -125, whereas the under is +105. This means that the Lions are currently slightly favored to win at least eight games in 2013.
Moving on to the Super Bowl, the Lions have 60/1 odds of being crowned champions of the NFL. Their odds of winning the NFC and reaching the Super Bowl are 30/1. That puts them in a tie with the Carolina Panthers and Philadelphia Eagles. Only the Arizona Cardinals have worse odds in the NFC, as they are dead last by a wide margin at 150/1.
