Michael Fiddle took Matthew Stafford under 255.5 passing yards. He noted the Colts have been the sharp side ATS, with the spread moving from +4.5 to an expensive +3.5, implying Indianapolis controls game flow. Indianapolis leads the league in drive-success conversion rate at an eye-popping 83.1%, meaning they stay on the field and bleed clock. Fiddle expects that time-of-possession edge to cap Stafford’s volume. The market’s consensus number already sits below 245.5, so Fiddle views 255.5 as a chance to capture closing-line value while betting on a methodical Colts offense keeping the Rams’ passing attack in check.
