William Byron is riding high off his historic Daytona 500 win. Was it enough to boost him to the top spot in this week's rankings?

Last year: Daniel Suarez edged Ryan Blaney and Kyle Busch in a three-wide finish. There were 10 cautions and an Atlanta-record 47 lead changes, alongside a pileup of at least 16 cars, the biggest in the history of Atlanta Motor Speedway. Last race: William Byron captured his second Daytona 500 win while narrowly avoiding a final-lap crash.

Here's who won the Daytona 500, how much the purse was for this year's race, and just how social media reacted to it.

Jimmie Johnson finished third in the Daytona 500, his best result in the race since winning in 2013. Johnson, a seven-time Cup Series champion, is now a team owner and driver for Legacy Motor Club. DAYTONA BEACH — Seven-time Cup Series champion Jimmie Johnson survived last-lap chaos at the Daytona 500 and savored landmark achievements as driver and team owner Sunday night.

Jimmie Johnson didn't win Sunday's Daytona 500, but he may have been the happiest man in Daytona Beach that evening.
