This was a good, important win. There are still things to work on, however. Mike Tomlin's work is far from done.
The Steelers are 6-2, a half-game up in the AFC North and ready for a big rematch with rival Baltimore next weekend.
They are a very good, very dangerous team. They aren't, however, a complete team.
They still need to solve the running game woes. They ran well, a hidden statistic thanks to Ben Roethlisberger's huge day passing, on Sunday, but didn't break anything worth mentioning.
They also need to tighten up their defense some. The Patriots had no business getting as close as they did on Sunday. That's not all on the defense, but the Steelers could've closed out some drives a little more effectively.
Their biggest work must come in the red zone on offense, where the team was largely ineffective on several drives. Keeping Shaun Suisham, who is not a pressure kicker and is becoming good at the easy miss, off the field is essential. Scoring touchdowns will beat teams. Kicking field goals on long drives will keep them in games.
That red zone inefficiency kept New England alive on Sunday afternoon. That can't keep happening.
