Greatest ever....... no such thing..... I mean will he be looked upon as one of the best in the sport 20 years from now? of course...... Is what he has done remarkable? without a doubt..... but. I don't see how you can say one driver is the greatest......
On any given Sunday, with any given circumstances, anyone can win. But there are few that can do it week in and week out. there are drivers that many can argue are "the greatest"..... Look at drivers like Curtis Turner and Tiny Lund.... many old schoolers will say they are the greatest, but there stats don't live up to that. Then again, Turner spent half of his career banned by NASCAR, and Tiny was so hard on equipment, he never got a decent ride ( but he did win Daytona for the Woods)..... Petty is beyond a doubt one of the greatest, and has the stats to prove it..... but if you look only at stats, there are two sides to that coin.... Pearson ran limited seasons most of his career, but has over 100 wins, and leads Petty by a few wins when they ran 1-2...... Gordon looked unbeatable in the 90's, now not so much..... Look at Earnhardt...... same kinda thing with him in the 80's.
The teams make as much of an impact as the driver..... when Dale had the Flyin Aces, and Shelmerdine as cc, Gordon with the Rainbow Warriors and Ray.... DW with the Dew Crew and Brew Crew with Junior Johnson..... It is alot to do with chemistry as much as skill behind the wheel. Very few that are where they are would be there without the skill.
The racing has changed sooo much as well. No more dirt, very few short tracks, all types of adjustments to make to car, so much technology
I saw an interview not too long ago with ( I think) it was Petty, and he was asked about the new drivers vs the old drivers, and if the new guys could do what they did back in the day, and his response was, if they ran like they did back then, you would stil see the same guys up front.....
Personally i think the driver today are talented, but I gotta think the pioneers were by far better drivers, given the equipment.... but the drivers today have it much rougher when it comes to gettin a good ride and beatin the competition.....
So the long answer to the qusetion is no, not greatest ever, but still pretty darned good. Ok i'll hush up now..........lol
