Khalil Mack's debut for the Chicago Bears was the story of Week 1 -- until Green Bay Packers quarterback Aaron Rodgers led a second-half surge en route to a 24-23 comeback victory on Sunday night.
Let us not, however, forget Mack's instant impact. Before the halftime gun had sounded, Mack had recorded a sack, a forced fumble, a fumble recovery, an interception and a touchdown. Where does his outing fit in the pantheon of immediate NFL trade dividends? Glad you asked.
Pro Football doesn't have a rich history of trades involving veteran players, although we have seen an upswing in significant deals during recent years.
