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.

Bitcoin's price has fully recovered from  its  recent slump after  JPMorgan CEO Jamie Dimon  called it a fraud and Chinese regulators cracked down on exchanges.
The cryptocurrency had a drawdown of up to 14% in the 10 days after September 12  when  Dimon  compared it to the tulip bubble of the 1600s and vowed to fire traders who used it.
By Thursday  bitcoin had all of the losses. It was up nearly 2% from the lows on the day  Dimon  spoke  at $4157.31 per coin at 10:28 a.m. ET.
The move illustrates bitcoin's wild volatility; it's gained 331% this year  unheard of for any major currency and most financial assets. It also shows why many Wall Street professionals like  Dimon  don't see it as a legitimate store of value but as a speculative instrument.

Robert Dudley  who will replace Tony Hayward on Oct. 1  promised changes in light of the environmental disaster. "There's no question we are going to learn things from this investigation of the incident " he said.
 Hayward has some sympathy in his native Britain  where many pensions rely on BP stock and some consider U.S. outrage at the company to be over the top. A recurring theme in newspaper editorials and discussions among many Britons is that there simply wasn't much one man could do in the face of relentless American wrath.
 "BP sends Tony Hayward to Siberia to appease US " read a headline in the Guardian.
 Hayward  who will stay on BP's board until Nov. 30  will receive a year's salary of 1.045 million pounds (US$1.6 million) as part of his severance package. His pension benefits are valued at about 11 million pounds (US$16.8 million)  and he retains his rights to shares under a long-term performance program that could eventually be worth several million pounds if BP's share price recovers.
 Hayward said it was right that BP embark on its next phase under new leadership  and expressed his condolences for the families of the workers killed in the explosion.
 "The Gulf of Mexico explosion was a terrible tragedy for which -- as the man in charge of BP when it happened -- I will always feel a deep responsibility  regardless of where blame is ultimately found to lie " he said.
 President Barack Obama  who once said he would fire Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 Dudley spent some of his childhood in Mississippi and worked for 20 years at Amoco Corp.  which merged with BP in 1998. He lost out to Hayward on the CEO slot three years ago.
Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 "Our concern is not who heads BP " Gibbs said. "Mr. Hayward is leaving. The key is that BP can't leave and should not leave the Gulf. ... They have obligations and responsibilities as the responsible party in this instance that have to be met regardless of who the CEO is."
