			You play with what you got.  Same advantage/disadvantage for both teams.  Life is tough!
 
 Narrower hash marks mean a greater advantage for runners, not as likely to go out of bounds.  I wonder how today's narrower hash marks in the NFL would have affected the records of a Jim Brown, the greatest running back of all time.  Also, when he started in the NFL, there was only a 12-game season and he never played in a 16-game season.  The game has changed.
