A consulting firm has produced a study that shows that concussions in the NFL declined from 2010 to 2011, principally because of a change in the kickoff rule.
Edgeworth Economics revealed Wednesday that concussions declined from 270 two years ago to 266 last year. Even more interesting was the fact that concussions that occurred on kickoffs declined from 35 to 20 over the same period.
Jesse David, a statistician and economist at Edgeworth, told the Washington Post that the reduction in kickoff-related concussions is “entirely” related to the rule change. It “did what they intended it to do.”
David seemed to suggest, however, that more work remains.
“With concussions, there is a general trend that continues to be up, although there was a slight decrease in 2011 for the first time in several years.”
