It was dirty, I've watched it a couple times now. But, to be honest, most Cut Blocks are. It wasn't illegal so Slauson shouldn't be fined or punished in anyway. This is on the NFL and Roger Godell, and if I was Houston owner I'd be leading the band wagon to making these kinds of Blocks illegal during play. Most of the time the damn defensive player can't even see the dude that's coming low cause he's locked up with someone else. I understand It's a part of an O-Lines game but too many injuries occur due to it and the NFL needs to take a long look at this.
For once throw the defensive players a bone when it comes to changing rules...
Edit: Was reading an article that was saying it may not have been a legal block and he may get fined. Who knows? I'm interested to see what happens. At first I thought it may be legal, still dirty but legal.
