The Final Minute Against Atlanta

I also question, why score on 3rd down, why not push the pile one more time and run another 40 seconds off before sending AK in for the score on 4th down. Yeah, you take a chance that you may not score on 4th down. But whats more likely, you don't score on 4th down from the 1 inch line or your D that sucks in final drives gives up a FG anyway?
NO HC anywhere would do that thinking " let me make it so we have ONE shot to win the game because I'll bet we get a DPI to set up a 58yrd winning FG"
