Pacman most definitely went to college under the rouse of being a "student athlete" , like many have. Pacman continued the "invincibility" he felt as a collegiate to the pros, mixed with his draft status. That caught up to him, without doubt. a perfect real life situation that mirrors what that prior system, and the hubris it enabled, played out like just like the fable of icarus, and flying too close to the sun.
His wings melted, and he crashed back to earth HARD.
