The problem is that the second down play ended (and the Packers took a TO) with 43 seconds left on the clock. A third down run was going to take at least 3 seconds; the 1st down and 2nd down runs both took 5 seconds off the clock, so Seattle would have been able to run out the clock anyways. MM's only chance was for Seattle to pass, the runner to fumble, or the runner to go out of bounds. It was stupid decision.
