I don't know how much- but I'd think that some cooks have "upped their game" by adopting some of the technique on that (and other shows).
Everyone has their own tastes. I've tried over the years to up my BBQ game and have tried competition style techniques. I think it definitely helped me achieve a better end product in a way that appeals to me. That's the key.
Ruined backyard BBQ? NO.
But it's ruined a lot of perfectly good meat with people trying some of the recipes and techniques. I've been caught a few times giving people's ribs a quick rinse in the sink to make it edible.
There are always great ideas to be adopted, and like 'Lawnguy' says, "There's always knowledge to be gained in anything you do."
I think 'dads4' caught the essence, "it's ruined a lot of perfectly good meat with people trying some of the recipes and techniques."
We have to took at things and realize that in competition bbq, you have basically one bite to "WOW" the judge with appearance, texture, and flavor. Transition these into a back yard cook and the first few bites would be good great, but soon the flavorings could become over-powering, the meat texture could seem off, making it not as enjoyable as one would think. I have also noticed, just as 'dads4' indicated, some given food a quick rinse just to make it more palatable.
The bottom line is that backyard bbq isn't a copy-cat technique simply because there is no single method or flavor profile. The major factor in creating good BBQ rub is that it is too subjective to our own individual tastes. I am sure that five different tasters could sample the same food at the same time and give you five completely different reviews. Regional and ethnic tastes are the greatest variables in our own personal likes and dislikes. Couple that with the fact that many people have no idea what real bbq is; I still know many who think that just because you use a sauce, that that is all that's required to constitute bbq (LOL).
I'm not saying to ignore what you see, because by all means, you can learn from the best as you experiment. Just don't confuse competition with backyard bbq.
Barbecue has always held a romantic allure ever since man first cooked meat over an open fire. Simply put, the best bbq in the world is the bbq you like best. My mentor once told me to always cook for yourself because you will always be your own worst critic. If you enjoy the bbq, then you have succeeded; if others also enjoy it, then that's like icing on a cake.
There is no cookie cutter method, technique, temperature, or flavor to making good bbq. If there was, we would only see one type of smoker, rub, or sauce available to use; there would be no differences. But fortunately for us 'we' are individuals with widely varying preferences and tastes.
