Absolutely agree, and you still kinda have to have respect for what they did, it's not easy to ever be as dominant as Gretzky was. I can't say I knew that, I always assumed he was the greatest because he has pretty much every record.
Everything is advancing all the time. Look at the NFL, the 73 Dolphins or 85 Bears couldn't beat the 08 Lions. I still have to respect that, because they were also working with primitive schemes, etc.
I don't necessarily feel athletes/teams lose points for that.
