Anthony Richardson's concussion earlier this year was self-reported. In years past, he wouldn't have been able to raise a flag to a dedicated neutral medical professional while the game was ongoing. He likely would have been told by the team that he just got his "bell rung" and get back out on the field.

A lot more players are able to report concussions, which is a good thing. Seems like this generation of players are also more aware certain actions will have on their long-term health and also feel comfortable reporting these issues.
