A Christmas story
The Cowboys' ill-fated comeback on Christmas night -- led by third-string quarterback Stephen McGee -- has to make the list. Kicker David Buehler's missed extra point left Dallas with a precarious two-point lead that ultimately cost them the game.
A Cardinals loss would have put them at 4-12, and with tiebreakers, in the two-hole behind Carolina. Would Ken Whisenhunt have spent that high of a pick on a corner, like he did with Patrick Peterson at five? If not, maybe Carson Palmer would have been throwing to Green after all, except out in the desert instead of Cincinnati.
Meanwhile, the Cowboys would've plummeted five spots from ninth to 14th. Detroit would have likely taken Tyron Smith, or forced Dallas to trade up to get their man.
