My dude, age has nothing to do with it. (I'm probably older than you think.) I've watched A LOT of wrestling (including most of the territories like AWA, WCCW/Global and UWF)
I didn't even think that was Savages' best Wrestlemania match. I personally thought Savage/Flair was comparable if not better and even Savage/Warrior was decent. (Both matches told a good story and had a lead up to the match that was just as good.)
What made the Savage/Steamboat match good was that they were allowed to have an old school 'Southern" style bout with lots of near falls. But to say it was one of the best matches of all time is blowing it out of proportion. Flair was having 5 star matches Barry Windham and Magnum TA during this same time.
BTW-That Wrestlemania III card was hot garbage. It only had two good matches on it. (Savage/Steamboat and Bulldogs/Santana vs. the Harts and Danny Davis.) I know..I ordered it.
You think WMIII was hot garbage, that's fine. Most wrestling fans would disagree with you, but you're entitled to your opinion. It's not my favorite WM, but I certainly recognize it as a great show. I too grew up watching many NWA territories, WCCW, WWF, AJPW, and NJPW growing up. So, like you, my opinion is based on watching lots of different styles of wrestling (from the 80s until now).
Savage/Flair from WM8 was great, and I would even go so far to say that was among Savage's top 5 best matches (maybe #5), but I wouldn't put it up with Steamboat/Savage since that told an even better story, Savage hadn't bulked up with roids yet (you'll notice, he is slower in his movements so he didn't get around quite as gracefully, and Steamboat/Savage had a better finish (so much better in fact, that it has been copied since then). Why do you think wrestlers (many of whom never worked in the WWE) cite it as one of the best, if not the best, wrestling match of all time? Did so many of them simply not watch NWA back on the day? No, it's because the match was perfect in everyway, had an incredible build up, and featured 2 of the top wrestlers in their prime. Furthermore, many wrestling fans acknowledge Steamboat/Flair as one of the greatest wrestling
feuds, but usually rank Savage/Steamboat above that if we're talking a single
match. If calling Steamboat/Savage from WM3 one of the greatest of all time is "blowing it out of proportion," then many magazines hyping up it's greatness, wrestlers who were inspired by it growing up, and those who still today carry over elements from it into their matches have been fooling themselves for over 20 years.
In regards to Warrior/Savage from WM7, it was certainly Warrior's best match, but no where NEAR as good as Steamboat/Savage if for no better reason Steamboat's offense was quite a bit better than Warrior's ever was, even nowadays. No fault of Savage's, since he worked a miracle carrying Warrior to a great match.
But at this point this is like comparing Godfather to Godfather II. Maybe you like Godfather more, I like Godfather II more. Either way, they're both classics.
In the case with Steamboat/Savage, it has been referenced so many times that it can't NOT be classic at this point.
