It's a good thing the helmet experts at USA Hockey, who know so much about individualized fit, would never put an entire team in the same helmet model. For those interested, the VT group already published a paper on the STAR hockey helmet rating, and it can be read for free, here: http://link.springer.com/article/10.1007/s10439-015-1278-7 Regarding fit, this section indicates to me indicates they are aware of the importance helmet fit plays with regards to not only lab testing but in real life head injuries. from page 10: The biofidelity of the impact model used for Hockey STAR was ensured through appropriate headform selection and comparison of acceleration traces with other data collected from hockey players. The NOCSAE headform was chosen because of its superior helmet fit at the base of the skull, and around the jaw, cheeks, and chin compared to that of the Hybrid III headform.11 A helmet that does not fit properly can shift on the head during tests, and if the contact area of the helmet padding with the headform varies from what is realistic, the effective stiffness of the padding will vary, potentially resulting in a mischaracterization of a helmet’s energy management capabilities.
