For a site that covers racial issues as often as Deadspin, it's struggled lately to simply identify people correctly.

The left-wing sports blog suffered its second embarrassing racial mistake in as many months Wednesday after posting a hit piece on a "white" NFL coach it didn't realize was biracial.

San Francisco 49ers offensive coordinator Mike McDaniel was targeted by Deadspin staffer "Sean Beckwith," whose premise was McDaniel was overhyped as a possible head coach in the league due to being a "trendy, young, white guy."

"Be careful what you tweet for, people of the online realm," Beckwith wrote. "Mike McDaniel, the San Francisco 49ers offensive coordinator who has gone viral for his ‘adorable’ news conferences featuring references to Mike Jones and engaging answers, is ticking off all the boxes to be the next trendy, young, white guy who takes a head coaching position before one of the many deserving Black candidates."

DEADSPIN UPDATES MIKE MCDANIEL HIT PIECE AFTER KNOCKING BIRACIAL 49ERS COACH AS ‘ANOTHER YOUNG, WHITE GUY’

McDaniel, whose 49ers will play in the NFC Championship game on Sunday, was repeatedly identified as "white" in the Jan. 22 piece – one part says, "Is he white? Yes." – before Deadspin posted a correction on Wednesday.

"We learned after the publication of this article that 49ers OC Mike McDaniel, whom we describe as a "white guy," is in fact biracial. The article’s original text remains below. We regret the error," it wrote.

McDaniel's father is Black and he gave an NBC Sports interview last year where he delved into his family background.

Deadspin was pilloried for the mistake and the premise of the post. One writer commented on what he viewed as a decline in quality at Deadspin, which once was known for breaking major sports news like the Manti Te'o girlfriend hoax. In recent years it has dealt with upheaval and has struggled to recover since a mass staff resignation.

"This is a glaring example of laziness, of course, but even ignoring this one post the content at new Deadspin is a clear, clear step down from the prior version, which wasn’t perfect but was certainly vital," Awful Announcing contributor Jay Rigdon wrote about the McDaniel error. "A lot of the Zombie Deadspin content seems to be chasing some mythical audience that wants pieces clumsily discussing the intersection of sports and societal change, while also not caring care about quality of writing or whether the posts themselves unwittingly undermine the causes they’re purportedly championing."

DEADSPIN RIPPED FOR REFERRING TO ESPN'S SAGE STEELE AS ‘THE BLACK CANDACE OWENS,' DELETING AND REPOSTING TWEET

The mistake followed a tweet last month referring to ESPN's Sage Steele as the "Black Candace Owens," suggesting the right-wing commentator was White or some other race. 

The tweet was later deleted and replaced with another tweet that read, "IDIOT OF THE YEAR #6: Sage Steele, the Candace Owens of ESPN," an apparent reference to Steele, who identifies as biracial, being referred to as "the Candace Owens of ESPN" during an October appearance on former NFL quarterback Jay Cutler's podcast.

OutKick's Bobby Burack said Deadspin could give itself that title for 2022 already after its latest error.

"While it’s only January, it’s hard to imagine anyone in sports topping what’s left of Deadspin in the idiocy category," Burack wrote.
