The NFL is chock full of assholes, many of whom have violent pasts. It's the nature of the beast. The Pats just got really unlucky that one of their assholes actually took part in a murder. I have no idea what the media expects them to have done differently.
To take this further, I was listening to D&C this morning (T&R were on a break) and they had a mouth-breather screaming that it wasn't bad that the Pats drafted Hernandez, it was that they gave him the extension. You see once the Patriots knew that Hernandez' palls were dirtbags, they should have released him on the spot. The caller is not the first person I've heard suggesting this and it wouldn't surprise me if other media members pick up this gauntlet (if they haven't done so already).
But let's walk through this scenario: Hernandez has done nothing wrong and for 12 months, the media is clamoring for NE to sign him "He's kept his nose clean! He's earned their trust!" but instead of doing that, the Pats let him go. Why? The Patriots don't offer any concrete reasons but leaks have suggested NE didn't like the crowd Hernandez was running with and didn't want an incident to happen.
If this scenario occurred, the media explosion would be enormous. Felger would mock "the Patriot Way" for months saying that "they can't have Boy Scouts and expect to win Super Bowls. What's going on over there in Foxboro?" Borges would dredge up the old Oakland Raiders and talk about how these people are "football playing men, who play a violent game and character can't be dictated." Curran would probably write some passive-aggressive column accusing Belichick of being a racist and wonder why there's a double-standard for Hernandez and not Gronkowski. Someone would end up writing, "Hernandez just smokes a little weed, it's not like he killed a guy." And it would go on and on and on and on for weeks and would compound especially if the Pats' offense sputtered or Hernandez caught 12 touchdowns for the Jets or the Eagles or someteams that "cares about winning".
The thing is, they wouldn't be wrong. We'd destroy the Patriots if they released or didn't sign Hernandez because of something he may do in the future. This isn't Orwell's "1984", we don't have Thought Police yet. This whole incident wasn't something that the Patriots could have been proactive about, they had to be reactive and they did a pretty good job, I'd say. However ripping Kraft for being honest, I'm sorry but Fuck You Felger. You ripped him last week when they sent out a press release, you rip him this week when he meets face-to-face with the beat writers. What do you expect him to do?
And furthermore what do you expect the Patriots to do in this situation. Aside from Rae Caruth, has this ever happened in professional sports. The Pats are kind of flying blind here and it's a no-win situation because they either look like naive morons or people who knowingly drafted a guy capable of murder. You take a chance on someone and they can supremely disappoint you, it happens in life. The media of Boston are the biggest collection of hypocritical babies in America. They always want everything both ways. It's infuriating.
