This is almost certainly correct. The best thing he has going for him is unlike almost anyone else he got immediate attention from skilled EMTs and doctors in the stadium. NFL stadiums have all sorts of medical equipment.I’m not a doctor, and I didn’t stay at holiday inn express last night, but generally with a serious trauma the EMTs are in radio communication with the hospital regarding what to do. And at an NFL game, there’s already doctors there. So even if the prognosis was very bad, I doubt they would say, eh we’re just gonna call it here and not hurry. It’s more likely a decision was made with and by doctors that he could receive better care stationary in the ambulance than hauling ass to the hospital.
Generally one needs to be rushed to a hospital to (1) receive that level of care and/or (2) need immediate surgery.
They were very likely to have been able to make a proper diagnosis at the scene and determined the proper course of care.
