said by The Dv8or:One may say that they don't buy products or services based on commercials and endorsers, but there's a very advanced psychology in advertising, and the subliminal messages being passed have a lot larger effect than a person realizes. Name recognition is major, and with an aggressive ad campaign, the company is basically building a visual and mental relationship with you.
I don't follow your typical stick & ball sports save for hockey, so I would be disinclined to purchase anything these Top 10 athletes would be hawking. However, slap your logo on a Nascar Sprint Cup race car and you can be sure that I'll purchase your product. I've been brand loyal to Nascar sponsors for decades.
