How are the Steelers a bum team? First of all, Steelers do not tank, they are not criminal tankers and bums.
Second, Steelers played tight games that went down to the wire against Seahawks, Niners and Rivers. They lost all three games, due to shooting themselves in the foot in the first quarter of each game. It's been that kind of season for the Steelers. But in spite of the slow start, in each game Steelers were very competitive and had chance to beat the Niners, Ravens, and the Seahawks. And they 3-4.
