I cant think of a track on the NASCAR schedule that changes more from one race to another than Daytona International Speedway. It is front and center for competitors preparing to do battle in the summer classic, and while Daytona 500 winner Denny Hamlin and his Joe Gibbs Racing teammates will certainly be among the favorites Saturday night, not everything they utilized during this years Daytona 500 applies to this next race ...Here is why.The inability to maintain full throttle: The Daytona 500 is, and always will be, the most prestigious race on the schedule. Teams spend a large portion of the offseason focused on it, then begin the year with a week of track time constantly searching for speed on a track fresh and clean.As the week goes along, the track gets slick, and by race day in February, many drivers wish they had obtained more grip versus whittling away drag, which leads to straight-line speed.Its a comfort versus speed thing, and evidence of the value of a comfortable car was watching the solo spins of pole sitter Chase Elliott and restrictor-plate master Dale Earnhardt Jr. in the 500.The key to winning the Daytona 500 is a combination of speed and handling, but the key to winning Saturdays Coke Zero 400 is handling ... and handling!Keeping your right foot to the floorboard will be difficult for drivers Saturday because the track in the summer months (even at night) can be difficult to navigate.The fastest, best drafting car is virtually useless if its driver has to lift off the accelerator through the turns and will be passed by all those that qualified behind it as a result.Dark horse: With a restrictor-plate race comes the possibility of a surprise or upset.At the top of my list is pole sitter?Greg Biffle.Greg is much like last weeks winner Tony Stewart in that he has had a brilliant career. He is in the late innings of it, but I believe there exists the potential for at least another win before he chooses to hang up his helmet.Greg may not get the attention of Stewart, or last years retiree Jeff Gordon, but he probably should get more than he has.After all, like Gordon, he has spent his entire career with one car owner. That is amazing in itself.On top of that, Greg is a former champ in the truck and Xfinity series, came within a whisker of a cup title and is a previous winner of this event.Dont underestimate the potential of Greg Biffle to find Victory Lane again. Owner Jack Roush was wise to discover him early, wise to retain him late.The bottom lineDenny Hamlin, Matt Kenseth and Martin Truex Jr. will be strong contenders Saturday just as they were in February. But charting your course to Victory Lane will require driver comfort versus driver speed, as the historic Superspeedway wont be as forgiving as it was in February.Evidenced by Earnhardts and Elliotts solo spins in the Great American Race, nothing at this track can be assumed -- or taken for granted.A near-perfect race behind the wheel, a near-perfect day on pit road and a spotter performing as your conscience will all aid in your chance of victory.From a simplistic standpoint, your ability to keep the right pedal planted to the floorboard probably matters most.
