Good luck on your bets Kraken but there is no evidence that this statement is true. In fact, there is evidence otherwise.
I think you are taking generalizations and trying to apply them to specific situations, a habit that you as a poster may have.
In this case, I don’t believe you know what this line “should” be and I don’t believe you understand the necessary adjustments to said line to account for field conditions at closing time.
But you still think weather wasn’t factored into the line. Why, because it rained last night and was cold? This simply isn’t the case.
Many posters may be, and have been, getting away with many forms of social analysis based on some author’s opinion or their own, with little real world corroboration, it happens around here.
But valid line analysis requires real evidence; few know what that is and making some up won’t lead to winners.
Good Luck with the bets.
