I have been a wrestling fan longer than most of you were born. I've lived through the Backlund title reigns and I can tell you that he (or someone like him) could not make it today. Today's wrestling is completely different than the old school. Those guys could perform 60 minute draw matches several days a week. But then again, in their day, they used wrestling holds to stretch out their opponents. Today's is mostly flash, speed, high impact or power moves so much so that the style could not last a 60 minute match. It's a trade off.
This being said, Backlund's style is the style of the old AWA. The man could and still can wrestle; as most pros have confessed. His issue was mike skills and getting merchandise sold. He was popular for getting the job done in the ring; sort of like the old movies of the silent anti-heroes of the generation in "Death Wish", Walking Tall" (not the one with the Rock). As strong as a wrestler he was, he couldn't sell the toys, shirts, etc. that McMahon needed to keep the WWF afloat when he almost went bankrupt. It's well known that by the time Wrestlemania hit, it was a gamble because he put up all of his assets into this one show. Backlund could not draw the response revenued from this PPV.
Now Angle is a style sort of like Backlund; but he has the mike skills to promote and is willing to adjust to the new style; unlike Bob. There is a reason Angle is revered; he, like Backlund, can actually wrestle...unlike most.
I still am wondering to this day how he hasn't made it in the Hall of Fame, but Howard Finkle has. His style is way too boring for today's audience, but give the guy his due...he's EARNED it.
