There’s no way Luhnow didn’t know what was going on. The MLB investigators, some of whom were former federal prosecutors, had multiple sources who said Luhnow knew. His interview was full of deflection, logical inconsistencies, and what appear to be half truths. He says MLB called him and said there were rumors of the Astros sign stealing but he didn’t do anything to look into it because they didn’t affirmative ask him to do anything? You gotta be fucking kidding me. And even if, for the sake of argument, that he somehow didn’t, MLB had put all GMs on notice that they would be held responsible for violations of the sign stealing rules. So at minimum, he should have known. Hell, I went to a bunch of regular season games that year where I was sitting behind home plate or first base and could clearly hear the bangs. Of course at the time I had no idea what they were, but Luhnow could certainly hear the same thing from the owners box just a few feet away.
