The offensive line is improved
Mike Preston of The Baltimore Sun put it well. The team finally found the right combination on the offensive line during their Wild Card Weekend victory over the Indianapolis Colts. With starter Jah Reid out, tackle Bryant McKinnie moved to left tackle. Michael Oher moved to the right side. Guard Kelechi Osemele moved inside to guard. The team's play dramatically improved. McKinne and Osemele can maul opponents in the running game next to each other. Ray Rice and Bernard Pierce could be the best 1-2 running back combination in the NFL.
It's not a perfect offensive line, but it's much improved.
The Ravens have regrouped
The loss to the Broncos was the nadir of the season. But look at what they've done since in the two games they tried to win: The Ravensbeat the New York Giants and Colts by a combined score of 57-23. This counts for something. I'd argue those two wins were both among the best four or five games the Ravens have played all season. It's mostly because of ...
The defense is far more dangerous
Baltimore had a poor defense most of the year. The Ravens look a lot closer to above average lately. Part of it is health. Haloti Ngata looks healthier, Ray Lewis is back, and Arthur Jones is playing well. Paul Kruger is playing the best football of his career and Corey Graham has proven to be a find at cornerback.
The defense wasn't that bad against Broncos
Joe Flacco is hitting big plays again
This is the thinnest of our reasons to believe in the Ravens. I'm reasonably confident the Ravens' defense can be competitive. Five years in, I'm still never sure which Flacco will show up. Flacco had five plays over 25 yards against the Giants. Against the Colts, Flacco averaged 23.5 yards per completion.
Flacco is capable of making any throw. He's capable of playing well, but tends to be very streaky. He's quietly on a bit of a hot streak right now.
