Wrong? Well, you do realize there are different statistical analysis in regards to presnap motion (rate%, rate% with set, rate% without set, etc.). But according to the rating used in the article you linked, they were middle of the pack when Dallas lost to Arizona, Philly, and the 49ers. They were tops in the league during their recent win streak. All this per your link which was one of the major points of the article. Quoted from the article "From Week 9 on? They've thrown more passes preceded by motion (125) than any team in football."
But I'm sure you will stay active here with their loss today. Keep following up on your promise to treat Dak how others mistreated Romo.
