Green Bay Packers (9-6) at Detroit Lions (9-6)

I always talk about the inconsistency of turnover margins and why using past turnover margins as evidence for predictions of future turnover margins is basically useless. The Packers are a great example of that. Through the first 12 games of the season, the Packers were -5 in turnover margin on the season, but over the past 3 weeks they are +12. Unfortunately for them, that works both ways and teams that have a +12 turnover margin or better over a 3 game span, on average, have a turnover margin of +0.0 the following week. Despite their recent run to put them in position to win the NFC North, the Packers rank just 12th in first down rate differential.

The Lions, meanwhile, rank just 27th in that metric, despite their 9-6 record, and actually have a -5 point differential on the season, as 8 of their 9 victories have come by a touchdown or less. That’s why this isn’t a bigger bet on Detroit, but we’re still getting great line value with them as 3.5 point home underdogs. This line suggests the Packers are about 6.5 points better than Detroit, which don’t make sense. About 1 in 4 games are decided by a field goal or less, so the Lions have plenty of room to cover even if they don’t win this game straight up. The Packers are just 2-5 ATS on the road this season anyway, with losses in Minnesota, Atlanta, Tennessee, and Washington, so I really don’t understand this line. Even just 2 weeks ago, the Packers won by just a field goal in Chicago and that was despite winning the turnover margin by 4, something they’re far from guaranteed to do again this week. If you can get more than a field goal, Detroit is worth a bet.
