I was recently watching a college football game and something happened that I did n't understand . There was a kickoff and the ball was returned to the 40 yard line with a blocking in the back penalty . The ball was placed on the 9 yard line and the first down marker was at the 23 . Why was that ?
2014 NFL Playoffs : In his 58-yard run against the Seahawks , did Colin Kaepernick run out of gas ? Why did n't he score ?
