What is the real argument concerning the length of games?
1. Fans are bored, therefore attendance declines.
2. Shorter games reduces injuries?
3. Equipment lasts longer, therefore fewer cows and trees are sacrificed.
Players, coaches and managers are going to get their time in, one way or another. You trim here, add there. Certain cirmustances will elongate games. How soon do you clear the field for an injured player? I know some of these are rare instances, but everyone is adding up every second.
