Jackie was one of the very top players when he played actively, period. Of course, he has not won many tournaments but we are talking about a period where there weren't nearly as many competitions beside Hekko's monthly 5v5, as there is today. Just because a few people mention him as part of the all-time greatness (which isn't true) doesn't mean he is one of the most overrated old gen players. I was about to say that you should know better Heri but as Porkins mentioned, you were barely playing at the time so how would you know what sort of impact he had?
Now, saying Evanovic, JackieChan or Axiom would come-back and destroy everyone is literally talking out of your arse. But at least that's nothing new.
