there is always a trade off. In Petty's and Pearson's day they didn't have bulletproof cars like JJ and Gordon did either. They also weren't having to drive to their next race and run then having to run the next day or two and didn't have a perfect backup car on the hauler to pull off to run. Two entirely different eras and situations. Put Petty and Pearson in their prime in todays cars and JJ and Gordon in the 60's and 70's cars with the crews of the day and would they do anywhere near what they've done?
