In thinking about Hernandez and his life choices vs. his opportunities that he so thoughtlessly threw away, I can't help but think that the guy had severe mental and emotional problems.
His choice was (1.) Play in the NFL, do your job, stay out of trouble and collect $40 million for your efforts, or (2.) live like a thug, get arrested, tried and convicted - lose everything and rot in prison for the rest of your life. Only someone who is insane, demon possessed or both would choose #2.
The worst of it is all of the people whose lives he wrecked in the process of choosing door #2.
