There is a big difference between Week 1 and Week 2 of the NFL Preseason. Week 1 is more of a backup riddled game, but Week 2 is when the starters usually start to get sprinkled in and get more game action leading up to the regular season.
For the Pittsburgh Steelers, Week 2 will mean more starters to see the field when the Kansas City Chiefs come to Heinz Field Saturday night.
This per Dale Lolley of DKPittsburghSports:
In Week 1, offensively the only starters who saw the field were offensive tackle Matt Feiler, who played guard, and James Washington, if you consider him a potential starter this year.
