Despite Chicago Bears loss, Khalil Mack's debut with the team seemed as advertised. Sometimes you can miss who trots onto the field for a particular play, especially on defense, where eleven different athletes are out there for any given down. But you can bet that Bears’ fans had their eyes trained toward the sidelines at Lambeau Field in the in the first few defensive plays to see when No. 52 was going to trot out. On the fourth play, that’s exactly what happened. Khalil Mack trotted onto the field in the white jersey and blue pants for the first time in his Bears career, eight days after joining the team in a blockbuster trade that shook the NFL and fired up a fanbase.
