There’s arguments you can always make regarding weather, but oddsmakers almost never move lines more than a point due to conditions because, over a large sample size, it doesn’t effect the actual strength of a team.
But if the wind/slick field is effecting the passing game, it makes 3rd and longs a lot tougher to complete. I’m not saying it will be a factor, as it rarely actually is. But I know which team is more likely to shut down the run on early downs, particularly if Vita is playing. The Packers run defense isn’t very good.
I’m just spinning this, admittedly, but point being that potential weather advantages can often go either way.
I’ve never subscribed to the idea that humidity effected the Patriots in Miami. Moronic coaching decisions and bad quarterback play were the problem. When players can’t run well or the ball is slipping off their hands, that would be one thing. Running Steven Jackson 12 times in a row, putting Gronk in as the (impossible to reach on a pass) hail mary safety over McCourty, Brady’s typical failures against those defenses...those were reasons for losing. Similar story with the Denver altitude. Unless you think the Patriots are different from the other 30 teams that also play in those cities.
