The wackiest Redskins preseason in at least a year rolls on, with Robert Griffin III set to address the media on Thursday. And now here comes Joe Theismann, agreeing with Brian Mitchell that it would be best for Griffin to remain as quiet as possible.

“You’re right: it’s time for Robert to be quiet,” Theismann told SiriusXM NFL Radio. “And the Redskins have basically shut him down. He gets one interview a week, per request and requirement by the National Football League. It’s time to just go play football. That’s what he has to do: just go play football. Because when you’re 5-15 [over two seasons] and you’ve got guys like Aaron Rodgers, world champion; Tom Brady, world champion; Peyton Manning, world champion; Eli Manning, world champion; Tony Romo, making leaps and bounds a year ago; Drew Brees; and the list goes on and on and on and on and on. And you were 5-15.”

Now, there is much that’s amazing in this whole business.

1) Theismann is arguably the most talkative quarterback in Redskins history, and possibly the most talkative human being in world history.

2) Just last week, Theismann approvingly referred viewers to the Wall Street Journal piece that argued Griffin’s troubles have been exaggerated, the one headlined “The Imaginary Struggles of Robert Griffin III.”

3) While Griffin has undoubtedly made verbal missteps, he probably talks about as infrequently as any starting quarterback in the NFL.

4) For example, Griffin has one fewer weekly radio appearance than his presumed backup, Kirk Cousins.

5) And yet it’s still hard to disagree with Theismann. Do we contradict ourselves? Very well, we contradict ourselves.

“He said, ‘I’m the best quarterback on this team, I’m the best in the National Football League,’ ” Theismann said. “Well, you’ve got to sit in a room with Kirk [Cousins] and Colt [McCoy]. You know, you’re 53 guys — now you’re 90 guys that sit together — but in the regular season, you sit in the quarterback room.

“And these guys have supported Robert,” Theismann went on. “You read the stuff that they’ve talked about: they’re rooting for him, they’re helping him, they’re doing anything they can. And then you sit down and say, ‘I’m the best guy on this team.’ No matter how you slice that up or try and sugarcoat it, it just doesn’t sit well, I think, from a teammate standpoint.”

Meanwhile, ESPN 980’s Chris Cooley added a possibly related although quite different suggestion: that Griffin needs to speak up more, in the sense of absolving his teammates from some of the blame they took after the Lions game last week.

“If I ran a post route and the quarterback threw a corner route and it was picked, and everyone in the media said, Cooley ran the wrong route, Cooley ran the wrong route, and then the quarterback didn’t step up and say anything for me, we’ve got problems, man,” Cooley said. “This happens more times than people understand, but this clearly happened in this last week with Willie Smith and the offensive line at times. …

“There’s enough people on this team that want to say, ‘Man, this isn’t the offensive line.’ But if you can’t address it as a man and say, ‘I messed this up, it’s not my guys, it’s not my teammates, I’m a leader of the team and I’m going to take this because it was mine in the first place.’ ”

Coach Jay Gruden, of course, has done just that with the offensive line. Whether Griffin will do the same remains to be seen.
