The first weekend without any NFL action has now come and gone. The end of the regular season marks a sad time in the sports calendar, the beginning of the withdrawal period and the long wait for September to bring back meaningful action from the nation’s most popular sport. To help cope with our new Sunday void, Extra Mustard is compiling our favorite 75 GIFs from the season, brought to you in three parts. It wouldn’t be right if we didn’t open Part I with the most GIF-friendly moment of the season, Mark Sanchez’s butt fumble. Oh and an angry Jim Harbaugh. Lots of angry Jim Harbaugh. Enjoy, and also check out Part II here and Part III here.
