I remember watching it with my Dad when I was 13 and he said to me "there's your next top star". My dad was a big Austin fan even before he took off in 1997/98, he just saw something in him from the start. Even at my young age I was impressed as well, I knew he was special and that promo was godly at the time. It still is amazing now.
I really didn't get behind Austin until those Bret Hart vignettes started to air. That's when you kind of knew he was without a doubt their future guy. You're use to the KITR winner being prominently featured especially for Summerslam but it seems like they only had filler for Austin until Hart came back.
