That diagnosis doesn't exist anymore because schizophrenia is now on a spectrum like autism, but the thought did occur to me because this time he sounds so calm in expressing paranoid ideations (tweaking people sound more like he did on his last round of videos, unhinged, impulsive, emotionally labile).
BJ is showing a complex, systemized delusional framework which is similar to what a paranoid schizophrenic (formerly called) would exhibit in these videos in the OP. But what research is increasingly showing is that CTE is also linked to this behavior and these sorts of delusional frameworks.
From some research (neurocognitive disorders are not my specialty) I am seeing that these complex, fixed paranoid delusions could be from only the CTE also.
1. Neuropathologically Confirmed CTE and Paranoid Ideation
In a landmark review of
51 neuropathologically confirmed CTE cases, McKee and colleagues found that
42% of individuals had documented
paranoid ideation, often in the context of other behavioral changes such as aggression and irritability
. Omalu et al. similarly noted instances of
social phobia and paranoia in their case series of former athletes

2. Behavioral Subtype of CTE with Psychotic Features
Stern et al. analyzed
33 retrospectively collected, neuropathologically confirmed CTE cases and identified a
behavioral–mood subgroup (22/33) characterized by early-onset mood and behavioral changes. While most attention has focused on depression and aggression, they also reported
paranoid ideation among these behavioral symptoms

3. Case Example: Post‑TBI Psychosis with Systematized Paranoia
Although not always confirmed as CTE until postmortem,
Gurin & Arciniegas describe a
23‑year‑old woman who developed
new‑onset, systematized paranoia four months after a motor‑vehicle accident causing diffuse axonal injury. MRI revealed chronic microhemorrhages in frontal and temporal lobes—regions implicated in both CTE pathology and psychotic symptomatology

It is possible that this is schizophrenia and CTE together, but that is the least likely scenario given BJ's age of symptom onset. It could still be drugs and CTE, but his presentation in these videos is not congruent with that.
What we know for sure is that he has high levels of brain trauma, so we would have to go with that as the most likely culprit at this point.
