Nope, the analysts are not saying that, only the fans are.
If you put todays Coldzera on the old teams they would win a lot more than what they did. The game evolves, the players get better and they develop better strategies, like in any game and sport.
Unless you really believe that the players, after 10 years practicing, they all got worse than before, there's no base to say Cold wouldn't perform with the old teams, this is pure fanboyism.
What you're doing is saying "Pelé was better than Messi" We all know it's not true, he was only more dominant.
