Steelers and 49ers go 4-3 so far. Many consider Steelers a bad team and the 49ers a mediocre team.
As I say though, the Steelers are incredibly inconsistent. Their schedule is moderate after the Colts, so they could keep winning.
49ers luckily get a bye week to give time for them injuries to heal. But after the rams their schedule is tough. Can definitely drop 5 more games to Seahawks x2, chargers, cardinals, Saints.
