Not sure why people always say this. That team had Denis Savard and a mix of awesome veteran forwards with 1,000 point careers, vets, young up & comers, etc, like Damphousse, Muller, Bellows, John LeClair and an underrated captain in Carbononeau. And the defense wasn't full of stars, but still solid with the likes of Matthieu Schnieder, Erik Desjardins and JJ Daigneault.
That's actually a pretty decent team, looking back it at it now. It's not flashy, but it's not the "worst".
And many players like LeClair & Damphousse went on to have really good careers after that Cup.
At the time, if one were watching in 1993 and would have compared that team to the Penguins, Rangers or Kings, it perhaps got that reputation. Because that was a Cup winner that didn't feature a Gretzky, Lemieux, Messier, etc, because that's what we were used to saying for a period of consecutive years.
