The New York Jets and Pittsburgh Steelers experienced the most change of any NFL teams in the last week.
New York acquired Davante Adams after its Monday night debacle against the Buffalo Bills.
Pittsburgh made the quarterback switch to Russell Wilson from Justin Fields now that Wilson is healthy to play.
Sunday night's contest in Pittsburgh has the potential to be disjointed and low scoring because of both defenses.
Adams has built-in chemistry with Aaron Rodgers from their time together in Green Bay, but it may take some time for the on-field sharpness to return between the two.
