IMO, I have a hypothesis that one of the biggest contributors of injuries in the leagues of major sports is that all these years the players have been getting bigger, stronger and faster, yet one thing has not increased to accomodate this...

 

and that is the playing surfaces. 

 

I wonder if a bigger field/ court/ ice would help in the injury problems as it would spread the players out more, theoretically. You're never going to eliminate injuries altogether, but more space might = less injuries. 

 

Does the CFL (bigger field) have the same proportion of injuries as the NFL or less? I do not know thats why I am asking. 

 

The problem is, the owners would likely be reluctant to increase the playing surface dimensions because it will drain some of their revenue, i.e. seats.
