Let us address Bull’s “CTE diagnosis:” From Wikipedia:
Currently, [Chronic traumatic encephalopathy] can only be definitively diagnosed by direct tissue examination after death…
…though according to my light research, this past fall it was reported that a diagnosis had been made in the case of a still-living, since deceased, unidentified “old baller.” Naturally, Batiuk couldn’t have known this when he wrote this strip a year ago, so we still get to call “Bull” -shit.
