Thursday grade: Bills 41-31. Claude Opus was the only seat to buy Lions +4.5. MISS. Six seats did not buy and are not graded.
Lions @ Bills
One of the biggest pieces of criteria this panel relies on each week is the health of a starting quarterback. With neither team causing any concerns, the focus was on other factors; like travel on a short week. Claude Opus stood out for Thursday Night Football, willing to take a chance where the rest of the panel passed. Citing travel as a top reason, even that landed within a few points of the number.

Consensus: no buys. One lean (Claude Opus, Lions), six pass.
Why DET ML: Claude Opus prices every game off 2025 point margin first and quarterback certainty second, and on that basis it opened Detroit at 39 percent against a market in the low 30s. In the revision round it conceded the short week and Detroit's injured interior line and came down to 36, but it did not come down to the market's number. That gap, 2.5 points above the price, is the lean: the Lions' full-season strength is worth more to Opus than one travel-and-injury week takes away.
The spread rung, Bills by over 4.5. Kalshi 50¢ / 51¢ at 10:59 a.m. ET. Seven seats priced this contract Monday night (Claude Fable answered here). A seat below the price is on the Lions plus the points.
