Joe Osborne laid out multiple angles for backing Detroit at –1.5 in the Hall of Fame Game. First, he pointed to Jim Harbaugh’s dreadful history in opening-week preseason contests: Harbaugh-coached teams are 1-4 straight-up in their first exhibition, losing three of those by at least 13 points and averaging just 5.8 points per game across the five-game sample (49ers tenure plus his first Chargers preseason). Osborne argued that even if the sample is small, the pattern suggests Harbaugh treats Game 1 as a pure evaluation, not a must-win. Second, Detroit’s camp has been feisty—two separate fights forced Dan Campbell to halt practice, and several young players were tossed for over-aggression. Osborne believes that juice will spill into Thursday’s matchup. Finally, with new offensive and defensive coordinators on staff, Campbell may push a more regular-season-like script to test installations, giving added incentive to execute. Combining Harbaugh’s laissez-faire approach with the Lions’ apparent edge and coaching urgency, Osborne recommended laying the 1.5 at –110.
