Preseason finales are supposed to be nothing games. Starters take a knee on the sideline, backups run vanilla stuff, and the total sits there as an afterthought. But the Bears show up in Nashville with more eyes on them than any preseason finale deserves, because Caleb Williams and this retooled offense are the story of the summer, and everyone wants a glimpse before Week 1 closes the curtain for real.
That is exactly what makes 37.5 interesting. If Chicago's staff decides to let their new pieces play a series or two longer than tradition dictates, the total has room to run. If this is standard fourth-preseason-game protocol, with both teams' rosters mostly fighting for a 53-man spot rather than a scheme rep, this number could get buried fast. The Titans, for their part, have their own late-summer decisions being made on this exact field.
Nobody is promising a shootout and nobody is promising a punt-fest. The only real question is how much football the two coaching staffs actually want to show the world before it counts. That is the bet: over or under 37.5 in a game where both sidelines control how real it gets.
