4th & 10 Achievement
4th & 100
Watch the 4th clip in 10 video lists.
Go to the NFL Now category. Press to enter the playlist. Now select the fourth video and watch it. Once the video is finished back out and select it again. You can repeat the process thus unlocking the achievement.
If on the off chance this does not work (it should), you will have to wait until the season kicks off and use the third option 'Game Center' to go through each game and watch the fourth clip.
