Maybe I could be wrong but I don't think that call was Hackett's fault. I think Michaels doesn't know what he's talking about. Looked to me like Lamont Jordan was supposed to go left but started making his own plans when he saw a linebacker there where he didn't expect it.
Even if he did actually call a dive into the line, you have to blame Vinny there. He has to see that blitz and change the play. My guess is they had the play they wanted but Jordan messed up.
I think the Dolphins will trounce the Jets but I worry about Houston. If ever there was a look ahead game, this is it.
