So it's being reported that the Atlanta Falcons are the clubhouse leaders to land the starring role on this season's version of "Hard Knocks," the HBO reality series during NFL training camp.And that's just fine with new Raiders general manager Reggie McKenzie, who is against such an open-book policy. Especially in his first year on the job."I like Raider business to stay Raider business, that's all," McKenzie said in his media conference on Wednesday. "You want people to be comfortable, let their guard down and not have that group here. I think that would be a little different. Players and coaches act a little different when TV cameras are rolling."McKenzie was smiling as he said it, but his meaning was true."If you ask me, I say, No," he said. "I wouldn't want to have HBO here, but I'm sure some of the players (might), and I don't know if coach (Dennis Allen) would want to have those guys here. Don't ask me because my answer is, Stay away."It's a 180-degree turn from former Raider coachfootball czar Hue Jackson and his personality. I have no doubt if Jackson were still running the football side of things in Oakland, the Raiders would have been a leading contender to be on the show this summer. HBO was certainly interested.
