This offseason he appeared to really unravel. Allegedly shooting two people who were described as friends previously, fights with his fiancé, constantly out at strip clubs, etc.
If I was to offer a theory it would be that the 41 year old guy Wallace is an OG who holds some rank in the streets and kept Hernandez protected when he was younger after his father died. I think during his time in college and initially with the Patriots he was able to separate himself from Wallace but once people heard about that money I'm sure they all came running back especially Wallace. Then last summer Wallace saw that Hernandez was involved in that dispute in the club and took it upon himself to initiate that drive by shooting under the perception he did it for Hernandez but it was really to have something to hold over him. I think the FL friend and Lloyd both had disputes with him and pulled out their knowledge of the double homicide during the verbal altercation as their trump card. Hernandez under the mentoring of Wallace decided to attempt to shoot his way out of the situation.
At the end of the day Wallace and OG's like that are predators who prey on younger kids for money, strength and much worse. A great example being the $1200 a month condo for drug distribution, obviously not needed for a guy with a million dollar mansion and a $40 mil contract. At the end of the day Hernandez actions were inexcusable just the same but I believe he saw no way out in his manipulated mind. Even now he's paying for Wallace's defense.
Like I said though just a theory. I could be completely wrong and maybe just trying to believe Hernandez isn't a complete narcissistic psychopath.
