I wouldn’t jump to CTE. There is a lot of theory and speculation surrounding cause, affect, symptons and commonality yet to make presumptions about CTE. I think there is something there. But let’s not all excuse behavior as a first thought because of concussions.
That said, there are some important details missing in the story that would allow some more focused speculation. Why was he at the hotel? Did he have a room there? Was there an altercation? Was he tested for drugs? Did he have a fever? Why was it thought he broke into a teammate’s house? Was he at a teammate’s house prior? Was there anyone at the hotel that he knew or wanted to see? How did he get to the hotel? Where did he go when he left the hotel and how did he get there?
Nobody was hurt, he wasn’t arrested, is this that important?
It may not be CTE, but this sounds eerily like it’s beginnings................
