Apparently the injuries on turf were really back this year. If I remember right the average is like 15-20% more injuries on turf. But it fluctuates so when you happen to get years of 20% more, 10% more, 5% more the NFL issues a press release that the difference has diminished and is not statistically significant, then when it goes back up to 20-30% the next year they don't release the numbers.
