The Green Bay Packers and the Dallas Cowboys have some things in common. Both teams are 3-1, and both teams lost their most recent games, which could be described as their first big tests of 2019. The Packers, four games into a brand new offensive scheme with new coach Matt LaFleur, head into Jerry World without their star wide receiver in Davante Adams. The Cowboys offense — who handily beat moribund Miami, Washington, and the Eli-led New York Giants — get ready to host the hated Packers without the support of their starting left tackle, Tyron Smith, who suffered a high-ankle sprain against the Saints.
