They did a little of that against Carolina as well.
They sent 5 early against Carolina, then late in the 1st and in the 2nd quarter they played the nonsense you described.
And Delhomme had all day to throw, just like Leftwich did very early in the game last night when they didn't send anyone from the 3-4.
Look at Pittsburgh and Baltimore's 3-4 defenses when they get pressure. It's when they send 5 or more people. Not 3 or 4.
But this is pre season, and the Dolphins were just experimenting with things. That's what the pre season is for.
When the Dolphins started doing what they did early in the Carolina game, in the 2nd quarter last night, they were getting through the starting Tampa's O-line like a hot knife through butter.. McCown and Freeman were getting hit and abused so much, they couldn't wait to get out of the game.. Did you see their eyes ? They were terrified.
