Grass ID

Trying to figure out what grass this is. I call it blue grass, I know cattle eat the heck out of but it turns an ugly brown color when it's ready to be baled. Only thing I don't like about it cause people think it's Bahia grass in a bale when it's not. It's a blue color when it's not over mature like so in the picture, yeilds right with coastal. Just wanna know what it is so I can do some research and decide if I want to kill it or keep it. Thanks
