Like it or not the champion becomes a role model. He's now the face of nascar. With MADD and DUI such a big part of life today I didn't see his actions as positive, especially for kids.
I never saw Sr, Tony, Rusty, DJ etc staggering around after they won.
Brad is not the face of NASCAR. Dale Jr is and has been for at least the last 10+ years. In fact, from what I've seen Brad was one of the most hated.
He was a 20 something multi millionaire who got drunk celebrating his first championship at the top level of a professional series. If anything, this would make him waaaay more endearing to fellow 20 somethings..... In fact I'm impressed he was able to stand upright and form a coherent sentence.
Sr, Tony, Rusty, DJ didn't have the misfortune of always having media in their face. Once the race was over, that was it. NASCAR is A LOT more personal these days than it has ever been. Some of it for good and some of it for bad.
For example: Back in the day, you knew Dale Sr was married to Teresa, and that he had four kids. Some people knew they were by different women, some didn't. It didn't matter. You either liked him or you didn't and that was almost solely based of his racing style.
Today, we know drivers who have cheated on their wives, what the woman's name is etc., we know the past lives of drivers fiancés', we know where drivers live, we know where they eat and play. I've seen drivers and their family and friends get brutally verbally attacked on social media over the tiniest of things .... I mean stuff that even made me want to cry and I don't even know them.
And before you say 'Well they don't have to put themselves out there'. Kelley and Dale Jr said in interviews that sponsors kept pushing for him to join social media and to interact with fans because it brought more money and awareness to their brands. He didn't do it because he really wanted to. Samantha Busch said that she and Kyle had to work with some of the KBM drivers to help with shyness and social media aversion.
I say all this to make the point, you can't compare what drivers back then did to what drivers today do because the way society works has changed. I'm pretty sure that if Tony or Rusty were in their heyday in the 2010s we'd be hearing A LOT more about their shenanigans. Hell, I still hear about Tony's shenanigans....
