That isn't the point. They don't have the speed, you are right. But these guys are right too, in that you haven't been around long enough to truly get it. It is like the Pats.
It isn't about whether or not they get it done. It isn't about them doing the impossible..it's just realizing how good that team is. How well they can execute, and how confident the team, and Jimmie is. Parallels to Tom Brady in terms of confidence. He's had 10th place speed for two years and still has won just as many races as Kyle Busch the last two seasons.
Put Jimmie near the front in a clutch situation, loosen the chassis, four fresh tires, and he will find you those extra three tenths and get it done.
Most clutch driver, most clutch team we have ever seen in the sport. That's the point. 2006, 2009, and 2013 were the only titles they were the fastest car all year long.
