With dirt & grass stains going to become obsolete? For what it is worth I have found by accident a seller who is buying brand new NFL football gear (being sold as such), putting some dirt stains on it and selling as GU from some pretty big name players...Not here to rip on anyone but most teams now play on field turf which leaves very unique black markings on cleats, jersey's etc...How many stadiums play on real grass?...Pittsburgh, Denver, Oakland, any others?
