News came out today that Aaron Hernandez's lawyer says that the CTE they observed in him is the most severe they have ever seen. Notice two things, this statement came from his lawyer, not the doctor and realize that Aaron Hernandez's estate is broke
He may very well have had CTE but if his lawyer will use this to try to explain his behavior in not biting. Aaron Hernandez was a bad dude way before he got to the NFL, why else would he have dropped so far down in the draft.
I'm sure that he did have CTE but I'm also sure he has more skeletons in his closet than Odin Lloyd and he started collecting those skeletons way before he got to Foxborough
