Detroit Lions vs Chicago Bears — DeepSeek betting tip 14 September 2025.

The Detroit Lions are rightfully favored at home against the Chicago Bears, but the betting value clearly lies with the underdog. At odds of 3.36, the Bears offer exceptional upside that outweighs their underdog status. Detroit's high-powered offense led by Jared Goff and Amon-Ra St. Brown deserves respect, but their defense ranked in the bottom third against the pass last season – a vulnerability Justin Fields can exploit with his dual-threat capabilities and upgraded receiving corps featuring DJ Moore and rookie Rome Odunze.

Divisional matchups historically produce surprises, and Chicago has closed the talent gap this offseason. Their aggressive defensive additions, including Montez Sweat and rookie Austin Booker, can pressure Goff into mistakes reminiscent of last year's turnover-prone performances. The Lions also face potential regression after their NFC Championship run, while Fields enters a contract year with explosive momentum.

Considering the implied probability of Chicago's odds (29.7% after vig adjustment) versus their actual win potential (estimated 32-35%), the expected value swings positive. At nearly 2.4x return on investment, the Bears' payout justifies backing an improved roster in a rivalry game where underdogs cover 64% of the time since 2020.
