I love the Tuesday Morning Quarterback. He has published his "immutable laws" of football. One of them is "take 3 till the 4th, unless you're way behind."
Here it is, about 2:20 left to play in the first half, Miami ahead 24-21, facing 4th and 1 at the 5. Points clearly will matter in this game, and Miami decides to go for it with a fade route to Haynos. Now, if it had worked, bully for Miami. But, it didn't, and KC charged down the field in 8 plays and scored a TD, stealing momentum as we went into the half.
In this case, I believe that they should have taken the 3; momentum would have remained with them, and they may have gone into the half with the lead.
And that brings me around to the simple point that Miami simply needs to play better. They played down to the competition for a couple of weeks, then struggled against the 49ers and Chiefs. They can't expect to beat the Jets that way.
Even if the Jets are mediocre.
