DAYTONA BEACH, Fla. — Denny Hamlin was all smiles and backslaps as he navigated the crowded Daytona 500 Club for NASCAR’s annual Media Day. He joked with Joe Gibbs Racing teammate Matt Kenseth in the midst of Kenseth’s live internet interview and later kidded with Kevin Harvick about his golf handicap.

Times are good for the reigning Daytona 500 champion.

In another four days, however, Hamlin will have to defend his title. And consecutive wins in this event are rare. Sterling Marlin is the last driver to earn back-to-back trophies (1994-95) in the Great American Race. Only three men in the race’s great history: Marlin, Richard Petty (1973-74) and Cale Yarborough (1983-84) have won back-to-back Daytona 500s.

Hamlin knows the challenge and the historical record. But he’s fast. And he’s a favorite.

His No. 11 FedEx Toyota led 48 of the 75 laps in Sunday’s The Clash exhibition and was out front when he collided with Brad Keselowski on the last lap.  A couple hours later, he was sixth in Daytona 500 pole qualifying.

"The odds are stacked against you," Hamlin acknowledged Wednesday of winning back-to-back Daytona 500 trophies. "If this were Martinsville I’d say the odds are really good, or Richmond. But at Daytona we know the entire field could win the race. We’ve seen surprise winners. There’s just more drivers that can win this week than say, next week in Atlanta. And it makes it very, very hard to repeat."

Hamlin’s competitors acknowledge the route is tough.

The late Dale Earnhardt made a great effort — winning in 1998 and finishing second in 1999. His son, Dale Earnhardt Jr. was runner-up in 2012 and 2013 and won in 2014 before finishing third in 2015.

Ryan Newman won the 50th Anniversary edition of the Daytona 500 in 2008. He finished 36th the next year. And that’s an equally as common turn of events.

"It is that hard to win a Daytona 500 in general," Newman said, allowing a smile. "So doubling up isn’t easy. It is challenging. You can have the best car and get shuffled out. You can have a not-so-good car and be stuck in the middle all day. It’s not easy. A lot of it is luck that you create. You have to put yourself in the right position. In 2008 we were fortunate to do that.

"And," he added, "I think it was easier to have a package that would dominate say 10, 15, 20 years ago. Just the way the rules are and everything else, we all kind of know some things like the No. 4 car (Kevin Harvick) guys did. You can’t do that kind of stuff anymore. So it becomes harder because of that. I think those rules have kind of communized the garage performance-wise."

Kevin Harvick hoisted the Harley J. Earl trophy in Daytona’s Victory Lane in 2007 and finished 14th both the year before and the year after. He acknowledged that the last to win two straight here, Marlin, competed in a vastly different time in restrictor plate racing.

"Those guys were dominant back in the 90s during that particular time period with the Kodak entry," Harvick recalled of Marlin’s wins.

"When you get to superspeedways like this there are so many things that can go wrong. There are more things that can go wrong than right. If you have a fast car or a slow car you can get caught up in a wreck, a miscue on pit road, hit a bird. You just never know what can go wrong or what could go wrong. Usually if it’s going to happen there’s usually some crazy event that happens during the Daytona 500, you just never know.

"And," he paused, "It’s just really competitive."

Michael Waltrip is a two-time Daytona 500 winner and very nearly captured three straight Daytona wins — with victories in 2001 and 2003 and a fifth place in 2002.

While acknowledging the odds are against a driver having both a super fast hot rod and everything fall right in competition, he immediately offered confidence in Hamlin becoming the first back-to-back Daytona champion in more than two decades.

"We might see it this year," Waltrip said. "Denny obviously was in a position to win Sunday (in The Clash), so we could very well see it this year. I know, like I had the best chance ever in ’02, and I finished fifth but that’s just what the results say.

"Part of my suspension fell off my car and went through Junior.’s radiator, took him out, and my car just drove terrible all day long, and we were the best car in ’02, and then we finished fifth. So it’s always something. This race is so difficult, and anything in the world can happen, and it’s hard to predict.

"But Denny could be the guy that does it."

And that’s something Hamlin absolutely agreed with.

"I do feel like over the past four years or so, I’ve always had a great shot," Hamlin said. "I’ve been smart enough to make the moves necessary to win it, but last year was the first time I did it.

"I always feel like we have a chance, that our cars were good enough to do it. I know that. But it just seems like we didn’t win it for some reason or another. But last year things came together for us and we executed a plan great.

"And this year I just feel like, if the chips fall right, we could do the same thing."
