Grass ID

mardi 10 juillet 2018

Just wondering if someone can give a positive ID for this. I never really gave it any thought until someone posted the same grass on another forum trying to get it ID and it went 4 pages with no positive answer. Most said it was Johnson grass and I can assure you it isn’t that it I’m not sure what it is though? It hasn’t been cut at all this year and is 10”.
