#1 Losing by a field goal to the Miami Dolphins
The Las Vegas Raiders managed to crack under pressure more than once when a win was on the line and nowhere was that clearer than their week 15 game against the Miami Dolphins. Not only was that evident by how the Raiders defense allowed a 20+ yard gain for Miami, but also how they notched a face masking penalty against their quarterback as well. One field goal later, and they were done. This should have been an easy win.
