As more information comes out about the rate of injuries in the NFL, a number of players are speaking out in favor of the real surface instead of the artificial stuff.
Los Angeles Rams star Cooper Kupp tweeted Saturday, calling this an "age-old issue" and one that is worth a discussion between players and teams.
Cooper KuppI believe that we -- and all teams -- should be playing on grass. <br><br>This is an age-old issue, and I believe the time to address the problem is now! <br><br>Let's have the conversation.<a href="https://twitter.com/hashtag/saferfields?src=hash&ref_src=twsrc%5Etfw">#saferfields</a>
This debate comes after ESPN's Kevin Seifert posted data on Twitter earlier this week showing the difference in injury rates between playing on grass and turf.
