How does VT correlate a particular helmet to the number of concussions likely in a season for a player wearing that helmet? Not every player plays the same game with or without reckless abandon. I find that conclusion of helmet model to number of concussions per season a bit of a scare tactic that the public won't take the time to read and think about. "I read it on espn.com. It must be true." Also, after watching the video on the top of the article, the dad of the 8th grade daughter that allowed his daughter to play a varsity level high school game(against players possibly 3-4 years older than her) is the one responsible for putting his daughter at risk. "Risk reduction" was a key phrase of the VT researcher. This dad did nothing to evaluate that. And finally, the helmet his daughter wore is 7500 NIKEBAUER helmet!!!! Refresh my memory: when exactly did Bauer buy Nike? What year, best case scenario, could that helmet have been manufactured in? That helmet was probably old when he bought it new for $70!!??? Sorry, but his particular situation slants the video quite a bit.
