LONDON (Reuters) -  When Comcast (CMCSA.O) boss Brian Roberts  was weighing up a $31 billion offer for British broadcaster Sky (SKYB.L)  a trip to see Skyâs products in store  and the knowledge of the London cab driver that took  him  there  helped to make up  his  mind.
 Chief Executive Roberts  said the visit was one of a number of things that confirmed Sky as a âjewelâ that his company should try to acquire  as Comcast looks to boost international revenues as growth in the United States slows.
 Roberts  said  he  had closely tracked what Sky had been doing for years  but last November   he  had an unexpected reminder of Skyâs influence as Europeanâs biggest pay-TV provider while in a cab with a colleague.
âI suggested that we jump in a taxi and go to one of the malls and get a demo of Sky in one of their shops. And we had a fabulous experience â  Roberts  told reporters on a call.
 Roberts  said that while the experience wasnât the deciding factor in moving forward with the bid  it reiterated the media groupâs value to the chief executive.

 Baker Mayfield  had been to this New York City ceremony before. This time   he  left with a statue.
There was little suspense Saturday night with the announcement that the Oklahoma quarterback is the 2017 Heisman Award recipient.  Mayfield   the fifth man to finish in the top four of the Heisman race three times  is the sixth Sooner so honored overall and the third OU signal caller since 2003 to claim the trophy.
 Mayfield  received 732 first-place votes  Love had 75 and Jackson  got 47.

 Mayfield   22  directed the nationâs most productive offense  averaging 583.3 yards a game  while leading the Sooners to another Big 12 title and a Rose Bowl date with Georgia in the College Football Playoff. His passing numbers were impressive enough â 4 340 yards with 41 touchdowns to just five interceptions and a 71% completion rate. But the fiery competitor did some of his best work in the biggest games  like his 386-yard  three-TD performance at Ohio State and his 598-yard day in a 62-52 shootout win against Oklahoma State. He capped the regular season with four scoring tosses in the Big 12 final against TCU.
"Wow. This is unbelievable for me "  Mayfield  said. "Being up  her  among these greats is something words can't describe. ... It's such an honor."

 Mayfield  â the first Heisman winner to begin  his  career as a walk-on since athletic scholarships started in the 1950s â is an old-school winner. For decades  seniors dominated the Heisman  but over the last 10 years four juniors  four sophomores and two redshirt freshmen have won the Heisman. By  comparison Mayfield  has been around forever  that first season at Texas Tech coming in 2013.  He  has played 47 college games. Only USCâs Carson Palmer with 50 had played more when  he  won  his  Heisman in 2002.
 Mayfield  is in many ways the perfect college football player: Good enough to play at an elite level  but because  he  is not an ideal NFL prospect   he  stuck around long enough to lead Oklahoma to three Big 12 championships and two Playoff appearances.
 He  also is among the most polarizing college football players of recent vintage.
 Mayfield  was arrested in February and pleaded guilty to three misdemeanors  including public intoxication.  He  was also punished by Sooners coach Lincoln Riley after making an obscene gesture toward Kansas players during a game in November.
And  in Week 2   he  showed  his  exuberance with an act that brought  his  first apology of the season.
After the Sooners' 31-16 win at Ohio State   Mayfield  ran around the field at Ohio Stadium with a crimson OU flag  then took it to the âOâ at midfield and tried to stick it in the ground as his teammates celebrated around him.
The next step for for the former walk-on: To once again prove some folks wrong. Listed at 6-1  220 pounds â and that might be a stretch  â Mayfield  is not the prototype NFL quarterback prospect  but that hasnât stopped  him  from becoming one of the most prolific passers in college football history.

COLO. SENATE CANDIDATE ROMANOFF BURNED BY THE TRUTH
 He told the truth.
 None of it compares with Romjue's concession to Politico that Romanoff's holier-than-thou stance on PAC money was  let's say  not as holy as you'd think.
 Romanoff's entire campaign has been based on the notion that Bennet has been corrupted by PAC money. There's the twin notion that Romanoff  though he took PAC money himself as the Colorado House speaker  has forsworn its influence and now sees a new and brighter way to conduct politics.
 Of course  the problem for Romanoff is that while the whole idea may sound good in a come-from-behind primary  it may not allow you to compete in a general election.
 And so when the news site Politico asked Romjue whether Romanoff would take money from the Democratic Senatorial Campaign Committee  he answered:
 Romanoff had been on a roll. Romanoff had caught Bennet in the polls. And Romanoff hit with his Bennet-is-a-looter TV ad  leaving Romanoff as the pure guy in the race.
 Romanoff's campaign had wisely avoided answering the DSCC question because there was no good answer. You can't really say no because everyone knows that eventually Romanoff would have to say yes.
 Romjue must have missed the memo. Here's how seriously Romanoff is taking this issue. He sent a letter to supporters  listing his home phone number and saying people should call him to discuss it.
 Yes. He actually includes his soon-to-be-former-home phone number -- you'd better call quickly. In case you don't call (and I'm waiting for Bennet to now tell his supporters they can drop by the house)  Romanoff says he'll take DSCC money only if PAC money is removed from his bundle. It's what the DSCC has done for Obama  who doesn't take PAC money.
