re: Your thoughts on the Damar Hamlin controversy ?

I don't think it was commotio cordis. CC is caused by a sharp blow of a fast moving object with a relatively small cross-section (baseball, hockey puck) so the impact is focused on one point. A football helmet or shoulder pad is going to strike with a much larger, flatter surface with the energy distributed over a much larger area. Plus, that hit wasn't overly violent by NFL standards. It just doesn't add up to me.
