Concussion - sideline protocol is merely theatre

I watched the hit that Manziel took, and he clearly had a head injury (dropping the ball as he went limp for a moment).

I was surprised to learn in another thread that concussion symptoms do not appear immediately and so a negative test on the sideline is basically useless and a kind of ‘theatre’ ie. Let’s show the fans we care about the issue by going through this process.

"Any guy that goes into the boards like that, the first thing is the trainer and the doctors, that's how it goes," Crosby said. "What you're talking about is the difference between checking with a doctor and entering concussion protocol, they're two separate things."...
