KANSAS CITY  Mo. â  Justin Houston âs once-perfect team had lost consecutive games after a pair of uncharacteristic showings. The Kansas City Chiefs defense couldnât stop anybody  and the offense suddenly lost its effectiveness in the rushing department  which had served as a calling card during the team's 5-0 start.
 Houston   a seventh-year veteran and one of the longest-tenured Chiefs  looked around the locker room  diagnosed the problem and decided he had to speak up.
âIâm from a big family  so I understand there are times to follow  and there are times to lead. There are times to speak up â  Houston  told USA TODAY Sports after Monday night's 29-19 defeat of the Denver Broncos. âWe just werenât having fun.
And  most importantly to  Houston  and his teammates  the Chiefs had fun in the process.

Example Input: Some market watchers say most such trading is conducted outside Germany  and Schaeuble said Wednesday that Berlin's move -- which applies only to domestic markets -- effectively bans naked short-selling only of German and Austrian government debt.
 "The criticism made of our plans that we are impairing trading of other European government bonds is unfounded " he argued. He added that the legislation will allow his ministry to authorize exceptions.
 Schaeuble said he acted after hearing that the European Commission wouldn't be able to propose rules on naked short-selling before October.
 He noted that a German decision earlier this year to introduce a levy on banks  which would pay into a fund to cover the costs of future financial crises  was followed by European proposals.

 Quincy Jones   the music maestro whose recent interviews have sparked furious rows among friends and admirers  apologized on Twitter Thursday for "silly" things he has said.
In a tweet   Jones  said  his  six daughters took  him  aside for a "family intervention" after two recent interviews led to public discussion of  for example  whether  his  late pals  comedian Richard Pryor and actor Marlon Brando  slept together.
Jones blamed age   his  giving up drinking three years ago and memory problems for  his  garrulous interviews in Vulture and GQ recently. Among other topics in the profanity-pocked Q&As   he  said  he  didn't care for Taylor Swift's music  once dated Ivanka Trump and once thought the Beatles were bad musicians.
"Even at 85  it's apparent that 'wordvomit' and bad-mouthing is inexcusable "  he  continued.  He  said  his  "bad-mouthing" contradicted messages  he  wanted to convey  about racism  inequality  homophobia and poverty.  He  said  he  had already reached out to  his  friends to apologize privately.
"But when you live a public life you have a responsibility to be an example & since I do live a public life I wanted to make a public apology "  he  wrote.
"I am sorry to anyone to whom my words offended & I'm especially sorry to my friends who are still here with me & to those who aren't "  he  wrote.  He  thanks  his  friends and family for their "grace."
"Thank you for calling me out when I've clearly made a mistake...many mistakes "  he  said. "I hear ALL of you & I thank you."
 He  signed it: "Love an 85-year-old bow-legged man who is still learning from  his  mistakes."
 He  did not explicitly retract  his  claim about Pryor and Brando.
Two weeks ago  after the Vulture interview began attracting a lot of baffled attention  Pryor's daughter  Rain Pryor  furiously denied her father and Brando ever slept together and poured scorn on everyone gleefully gossiping about it  including her father's widow  Jennifer Lee Pryor  who confirmed  Jones ' claim.
In two lengthy online diatribes  Rain Pryor denounced  Jones  and  her  stepmother.
