The choice of head gear is important for Green, who is in his second stint in his hometown of St. Louis. Each of his past two seasons were cut short by concussions when he was with the Chiefs in 2006 and the Dolphins in 2007. He didn't play after suffering a concussion in the fifth game last year.
This preseason, Green has been experimenting, wearing a different helmet style in each of the first three games, trying to find the best fit.
