Their season, like their team identity, is splintering more every game.
The Ravens produced more turnovers (two interceptions and a fumble) than they did scores (two field goals). Their last mistake - Lewis' fumble at his 33-yard line - proved to be the Ravens' undoing, setting up Olindo Mare's game-winning, 43-yard field goal 6:12 into overtime.
For a Ravens defense that held the Dolphins to 267 total yards and no touchdowns, its reward was mounting frustration for the second week in a row.
"We'll always stay together," linebacker Ray Lewis said. "We understand what a team is."
The Ravens' second straight loss - their first losing streak of the season - dropped them to 5-5 and virtually out of first place in the AFC North. Although they have the same record as the Cincinnati Bengals, the Ravens are actually behind them as a result of a tiebreaker, with their loss at Cincinnati a month ago.
"In every season, there is a defining point on how a team becomes a team," left guard Edwin Mulitalo said. "I think this is going to be one of those times. Remember back to the 2000 season when we stuck together. That's the main focus for this week."
Those 2000 Ravens rebounded from a five-game touchdown drought to win the Super Bowl. Unlike that team, this year's Ravens offense has become an oasis for the opposition.
The Ravens have turned the ball over 10 times in two games, giving up 26 points in the process. Jamal Lewis, in particular, has fumbled three times the past two weeks after coughing it up just once in his first eight games.
But Lewis may not be solely to blame.
The league's leading rusher had missed the previous two plays because he aggravated his right shoulder sprain but he said it was all right on the fumble.
He then repeatedly sidestepped the specifics of the fumble, saying he first needed to look at the film. Although it looked like Lewis just dropped the handoff, there was speculation that new quarterback Anthony Wright, who was filling in for the injured Kyle Boller, didn't use the right footwork in giving Lewis the ball.
"I don't want to blame nobody; I don't want to blame myself," said Lewis, who was held under 100 yards for just the third time this season. "We just turned the ball over, and we just can't do that in that time of the game."
The Ravens gave Miami (6-4) its first points of the game, too.
Wright's first pass of the second quarter was underthrown deep in the middle of the field and was picked off by Sam Madison. Seven plays later, Mare hit a 23-yard field goal to put the Dolphins ahead.
The Ravens' only points of the first half came as a result of Lamont Brightful's 73-yard kickoff return. The Ravens, who had the ball at the Miami 15 (the closest they got to the goal line all game), moved back 6 yards on three plays and settled for a 39-yard field goal to tie the game.
There were no more red-zone struggles since the Ravens didn't get a sniff of the 20-yard line for the rest of the game. The Ravens finished with 220 yards of total offense, their lowest output of the season.
"It's time for us to take accountability for the offense and give this defense some kind of help," receiver Travis Taylor said. "The way they've been playing the last two games, what else can you ask from your defense?"
