Saw this quote from Marcus A'Richtius on the Lord Saybinz rule.
"I feel like if you can train offensive players to play five or six plays in a row, you can train defensive players to play that many plays in a row, too," Richt said. "I personally don't think it's a health issue deal, but if there's some evidence otherwise, it will be interesting to see it. ... I think it's somebody's assumption. I don't think there's any hard evidence on it."
