Power Rankings - Power Rankings: If it's Bristol, Kyle Busch undisputed No. 1

People want to call him the "new" Kyle Busch. But he looked a lot like just plain old Kyle Busch this weekend at Bristol Motor Speedway.
That's the Kyle Busch who is in Victory Lane more often than not at the .533-mile speedway and added a couple more wins to his total with a sweep of the Nationwide/Sprint Cup series races this weekend in "Thunder Valley."
That's five in a row at Bristol for those of you keeping score at home, spanning the Camping World Truck Series, Nationwide and Cup divisions. And when NASCAR heads back to Bristol for a tripleheader this August, you can bet Busch will be in the equation all three nights again.
While winning in the truck and Nationwide divisions is certainly satisfying to Busch, the big picture of course is the Sprint Cup effort. The repeated knock on Busch in NASCAR's top level has been his perceived inability to harness his emotions and focus on winning a championship.
Time and again Busch has proved getting to Victory Lane isn't as hard as dialing down what's bubbling up inside him, which sometimes spills over and gets in the way.
Whether it's a an on-track run-in with a driver, a tirade over his radio with his crew or a double-bird salute to a NASCAR official, Busch has found ways to create challenges that have so far proven to difficult to overcome to challenge for a title.
Perhaps we're seeing that change in 2011. True, there is a long way to go, and with only four races in the book, a lot can happen to upset anyone's apple cart. But so far, Busch has tempered himself and dealt with both adversity -- like an engine turning his car into a fireball at Las Vegas -- as well as triumph, as in his trip to Victory Lane on Sunday.
More wins certainly appear to be in Busch's future. Whether those can add up to being a championship contender still remains a question.
