Updated MAY 30, 2015 11:55p ET  Denny Hamlin and Jimmie Johnson, two of the heavyweights of the NASCAR Sprint Cup Series, are the heavy favorites to square off on Sunday at Dover International Speedway, site of the Fedex 400 benefiting Autism Speaks.  Each man has gotten the better of the other at times, with Johnson scoring a knockout blow in the final race of the 2010 season to wrest the championship away from Hamlin at the last moment. Sunday's race could turn out to be a classic battle between the sport's two best teams and two of the best drivers.  Certainly, there are 41 other drivers in the race, with about half of them having legitimate chances to win. No one would be surprised if Kevin Harvick or Joey Logano or Kurt Busch won at Dover on Sunday. For that matter, all four Joe Gibbs Racing drivers, including Hamlin, finished in the top five in Saturday afternoon's final Happy Hour practice.  That said, Johnson and Hamlin are the favorites to win on Sunday. Here's how they stack up:  Speed: Hamlin qualified his No. 11 JGR Toyota on the pole, was fastest in both Saturday practices and was second Friday's lone round of practice. Johnson was fastest in Friday practice and fourth and sixth on Saturday. Inexplicably, Johnson qualified 14th, as all the Hendrick Motorsports cars struggled in qualifying. Advantage: Hamlin.  History: Johnson has nine victories and 14 top-five finishes at the Monster Mile. Although he's run markedly better in recent years at Dover, Hamlin has never finished better than fourth here. Advantage: Johnson.  Momentum: Hamlin gave JGR its first victory in the NASCAR Sprint All-Star race two weeks ago and nearly won the Coca-Cola 600. Johnson, meanwhile, had a rotten two weeks at Charlotte. On the other hand, Johnson is the only driver with three Sprint Cup victories so far this year. Advantage: Even.  Team speed: As a group, the JGR Toyotas have been faster than the Hendrick Motorsports Chevrolets so far at Dover. All four JGR drivers qualified in the top 10; none of the Hendrick drivers did. In Happy Hour, all four JGR drivers made the top five, while Johnson in sixth and teammate Jeff Gordon in ninth were the only two Hendrick drivers in the top 10. Advantage: Hamlin.  Track position: Because he qualified on the pole, Hamlin gets the coveted first pit stall, a huge benefit at Dover, which has one of the tightest pit roads in all of NASCAR. Advantage: Hamlin.  Career stats: Johnson has won six championships, including the one he stole from Hamlin in 2010. Johnson has 73 career race victories and a winning percentage of 15.1. Hamlin has 25 victories, a winning percentage of 7.4 percent and no championships. Advantage: Johnson.
