Strength Edwards won the last two races of 2010, and he believes his team has figured out a setup secret on his number 99 Ford that will carry over into this season.
Weakness Aggressive behind the wheel—he sent Brad Keselowski into the fence at Atlanta—Edwards has few friends on track. He needs to show more patience in the game of give and take.
Bottom line If a driver from the powerful Roush Fenway Racing team is going to take down Johnson, it will be Edwards.
3 KYLE BUSCH
2010: 3 wins, 18 top 10s, 8th in final standings
Strength The younger Busch brother is widely regarded in the garage as the most talented driver in the sport, as he consistently exhibits more car control than anyone else in NASCAR.
Weakness An all-or-nothing driver, whose emotions have been known to get the best of him, Busch is often a wreck waiting to happen.
Bottom line Busch may well amass the most victories in 2011, but until he reduces the number of on-track risks he takes, he won't win the Cup.
