We've got another couple potential wind spots in NFL Week 10, so I did a little digging... The sweet spot for unders appears to be right around 25 miles per hour:

15-19 mph: 79-83-2 (-5.2% ROI)
20-24 mph: 13-20 (-23.2% ROI)
25+ mph: 10-3 (+48.3% ROI)

The main takeaway is this -- the wind (and weather in general) is overvalued in the NFL until we start getting to really extreme outcomes. In those rare situations, it becomes undervalued.

Packers vs. Jaguars and Browns vs. Texans look like they qualify as outliers this week (current forecasts for 29 mph winds)

Totals in these games have adjusted, but they're still probably too high

I would also avoid the passing games in these spots like the plague in DFS
