The top pre-cap teams were exclusively built upon drafted and developing a top core.
Detroit didn't bring in Yzerman, Federov, Lidstrom, etc as free agents. Likewise, Colorado and New Jersey with Niedermayer, Elias, Brodeur, Sakic, Forsberg, Hejduk, Tanguay, Foote, etc as players they didn't bring in as free agents.
The Rangers tried building a winner through free agency and they always failed. Their most recent Cup win was built upon guys like Leetch, Richter, Zubov, Kovalev, which they supplemented with experienced vets like Messier, Larmer and Lowe that they acquired in trades.
Assen na yo!
