Yeah...this is where I'm shocked the Seahawks let the clock run down so much. With only 1 time out left...I think the smartest play is to try to run first. Do it with about 38-40 seconds left...so you use the time out with just over 30 seconds left if unsuccessful. Now, you are free to still do whatever you want...because you can call two plays in the time out, and a failed run on 3rd down still gives you 25+ seconds to set up for another play. If you wind down the clock too much, it makes your play-calling more predictable. You can't worry about leaving time on the clock in that scenario...you need to use the clock in whatever manner gives you the greater advantage on the field to score the TD you need to retake the lead.
