Lions Favored by a Field Goal, Cardinals Getting Points at Home
The Detroit Lions travel to Glendale to face the Arizona Cardinals on Sunday, October 11, with a 1:25 PM PDT kickoff. The market has made its verdict clear: Detroit is a meaningful road favorite, installed at -5.5 on the spread across most books and carrying moneyline odds that reflect a roughly 71-72% implied win probability. Arizona is the home underdog, but the points and the price on their side of the ticket are drawing attention ahead of a spot the Cardinals can keep competitive.
Here is what the current lines tell you about how oddsmakers view this game.
Detroit Lions vs. Arizona Cardinals Spread: Consensus at -5.5, Key Split at -5
The majority of sportsbooks have landed on Detroit -5.5. You will see that number at BetRivers, BetUS, Caesars, DraftKings, FanDuel, GTbets, Novig, and several other books, with -110 juice on both sides standard at most of those shops.
The notable exception is BetOnline.ag and LowVig.ag, both posting Detroit -5. That half-point difference matters in NFL betting. Getting Arizona +5.5 instead of +5 gives Cardinals backers coverage on a field goal game. If Detroit wins by exactly five, bettors at +5 push while +5.5 bettors cash. If you like Arizona to keep it close, +5.5 at standard juice is the better number. That said, LowVig.ag's -105 on both sides of the -5 is worth considering for Detroit backers who want to save on juice.
The half-point hook is one of the most important concepts in NFL spread betting. If you need to translate any of these numbers, the Odds Converter is a quick reference.
Moneyline: Detroit Around -250, Arizona Between +188 and +205
On the moneyline, Detroit is priced between -244 and -256 at mainstream US books. FanDuel and BetRivers are at -250; DraftKings and Caesars are at -244. At -250, the implied win probability for Detroit works out to approximately 71.4%. Arizona sits between +188 and +205, with FanDuel offering the best publicly available price at +205.
There is meaningful variance at sharper books and prediction markets. Kalshi has Detroit at -213 and Arizona at +203, while Novig shows Detroit at -227. Those numbers suggest the true market probability on Detroit may be softer than the -250 offered at traditional books.

Totals: Market Clustered Between 52 and 52.5, FanDuel Low at 51.5
The over/under is the most dispersed market in this game. Most books are settled between 52 and 52.5. BetUS is the high outlier at 53, while FanDuel sits low at 51.5. The full-point gap between those two books creates a potential middle opportunity if the game lands on 52, though you would need to hold positions at both books simultaneously and account for juice on each side.
BetRivers is posting 52 with -108 over and -114 under, making the over the more expensive lean at that number. Caesars has 52.5 with the under juiced at -114, a signal that sharp action may be leaning slightly under. Book selection matters as much as the pick itself in this market.
What to Watch Before Kickoff
Injury Reports
Detroit's offense runs through Jared Goff's decision-making and the strength of the offensive line. Any news affecting skill players or line depth will move this spread. Arizona's offense runs through Kyler Murray, and his health and mobility will be a significant factor in whether the Cardinals can stay in this game.
Line Movement
The presence of -5 at BetOnline and LowVig.ag alongside -5.5 at most books reflects some market disagreement on where this number belongs. Movement toward -6 would signal growing confidence in Detroit. A reverse move back toward -5 would suggest Arizona money coming in. Tracking sharp line movement ahead of kickoff can clarify where professional money is going.
Home Field and Situational Factors
Arizona plays its home games in a dome, removing weather as a variable. Controlled conditions tend to favor passing offenses and can push totals higher. Detroit has one of the stronger offensive rosters in the NFC, already reflected in this number, but road games against motivated teams carry variance the market cannot fully price.
