What to keep an eye on in regular-season game No. 2 against the 49ers:
WELCOME BACK:**The Steelers will be making their 2015 Heinz Field debut. Will they be able to feed off the energy the occasion is certain to generate?
SPREAD THE WORD:The Steelers had communication issues in their opener at New England that resulted in defensive issues that included blown coverages and unguarded receivers. Can they get that stuff fixed and keep it fixed?
Here is a look at each the statistical leaders for both the Steelers and 49ers heading into Sunday's week two matchup at Heinz Field.
CONTAIN COLIN:**49ers QB Colin Kaepernick is an accomplished runner and isn't shy about contributing with his legs as well as his arm. The Steelers need to stay disciplined as well as aggressive on the pass rush and avoid making it easy for Kaepernick by providing him lanes to scramble through when the mood strikes.
FINISH THIS TIME:The Steelers kicked field goals on possessions that reached the Patriots' 26- and 1-yard lines in the regular-season opener. That's not what they're after. The same can be said of a defensive effort that permitted touchdowns on all four New England possessions that penetrated the red zone.
BIG BOY PADS:San Francisco rushed for 230 yards in its opener against Minnesota and lined up with three tight ends in the game 37 times. Secondary issues or not, the 49ers figure to test the Steelers' run defense early and often.
