They had finally found their identity in the running game, it seemed, with Bush reeling off one big play after another. The minute he went down against the Jets, though, the Dolphins offense put the brakes on fast.
The Dolphins were moving the ball 5.2 yards per play in the first half, compared to just 4.8 yards per play in the second half. Ryan Tannehill was 6-of-11 passing (54.5 percent) in the first half, and 10-of-25 passing (40 percent) in the second half.
That only begins to describe the inefficiency for the Dolphins.
The cliché about playing a full 60 minutes of football came to be for a reason, possibly spawned from something that looked similar to the 2012 Dolphins as we have seen them thus far.
In both of Miami's losses, the Dolphins have played a solid 50-plus minutes. It's been the other 10 minutes that have left them at 1-2.
That is what separates the good teams from the bad ones. The Dolphins are trying to change a losing culture. That often involves some growing pains.
One of the most painful of growing pains is turnovers.
The Dolphins have lost the turnover battle by three (six giveaways, three takeaways). Twice in the first three games, the Dolphins have turned the ball over on back-to-back plays. Those are mistakes an offense can't afford to make, especially one with a rookie quarterback under center. That is especially true when the quarterback is completing 52.9 percent of his passes (54-of-102 passing).
If the Dolphins want to be a winning football team, they must also become a 60-minute football team.
The chances of them being able to do so decreased significantly when Reggie Bush went down, and if he isn't back soon, those chances don't figure to get better unless the Dolphins as a team get a lot better.
