There was a time, as recent as a few years ago, when if you asked NFL owners or executives if the league would ever have a team move to Las Vegas, the answer you almost always got was: "No effing way."

As the months have passed since, and as the NFL's dance with Vegas continued, people began to tell me the odds were increasing, like a thermometer reading from the fall to the spring. The percentages of the chances rose from 0 to 10, then 10 to 20, then higher.

Then just recently, in a conversation with an NFL owner about the Raiders and Vegas, I heard something that clarified just how far this has come. This owner said the percentage of the Raiders moving to Vegas "is now 50 percent—and maybe as high as 75."
