The players aren’t the only ones who need work during the NFL’s preseason; broadcasters are rusty, too. During the third quarter of Saturday’s Redskins-Packers game, TV analysts Joe Theismann and Charley Casserly were discussing Redskins safety D.J. Swearinger, an offseason free agent signing. Theismann talked about how the 25-year-old has played with a chip on his shoulder during his career, and wondered why so many NFL talent evaluators passed on Swearinger after his standout career at South Carolina.

“Charley, why does a guy like that, with the career he had in college, not get taken in the draft?” Theismann asked.

“It’s hard to say, Joe, with guys like that, whether it was size or speed or whatever,” Casserly replied. “I couldn’t really give an answer specifically for him, but safety’s a hard position to grade, Joe. They’re not on the tape very much. They have maybe five plays a game. You find more later-round guys taken at the safety than at other positions.”

Except Swearinger was drafted by the Houston Texans in 2013. He may play with a chip on his shoulder, but if that has anything to do with draft day resentment, it’s because he was taken in the second round — 57th overall, six picks after Washington selected David Amerson — instead of the first. Casserly and fellow NFL Network analyst Daniel Jeremiah even talked about Swearinger as a possible fit for Washington in the 2013 draft. (Look, it’s probably not easing prepping for preseason games, with 90-man rosters and multiple guys wearing the same jersey number, but Swearinger isn’t some fringe player just hoping to make the team.)

After several viewers tweeted about the goof, Theismann acknowledged his mistake on Sunday morning.

Swearinger had a good laugh over the error and suggested that somebody tell Theismann to look up his résumé.

“I went 2nd round sir!” he tweeted.
