I would submit that a review of the matter by a highly regarded neurosurgeon qualifies as slightly more than, “speculation.” It may be opinion, but it is certainly a highly educated opinion formed by years and years of experience

Dr. Ben is neurosurgeon, not a spine and neck specialist. He doesn't necessarily have any special expertise in neck injuries.

But, there was an offensive lineman, Mike Utley of the Detroit Lions, that broke two vertebrae at the base of his neck while falling face first on astroturf. His head and neck ever came in contact with another player during the injury. Maybe Dr. Ben can tell us the difference between Utley's injury and Gray's injury but I doubt there is much of a difference.

“Mike Utley of the Detroit Lions, that broke two vertebrae at the base of his neck while falling face first on astroturf.”

He was also running at full speed, had a helmet that torques the neck more on a fall (design since changed), and weighed well north of 200lbs.

Umm, the neck and spine are key components of the nervous system, which neurosurgeons specialize in, so yes, he is actually a spine and neck specialist.
