Except in that scenario, they have a longer field goal, and they used less time for each of the 3 plays. It's possible that Dallas misses the FG, leaving Detroit only needing about 30 yards to tie with their own FG.
Looks like this is a week by week debate. Ok the Texans are the most pathetic this week. Keep your heads up though Texans, The Cowboys wont let you hold the title for long.
