Ben Wallace was the best player on the 2004 title winning team though.

Everyone can see you just assess “talent” by glancing at points per game, which is why obviously teams like the 2003-05 Pistons do not count. Yet Luka made the conference finals with a better defence than offence. The Steve Kerr Warriors have almost always seen their defence hold up better in the postseason than their offence. The 2011/12 Bulls were led by Derrick Rose… and a pair of -6 relative defences. And then of course you have players like Hakeem Olajuwon and Tim Duncan and Kevin Garnett, who were all offering similar or greater defensive impact as those names you just listed, except with the added benefit that they were all capable on offence too.
I will give you a modicum of credit in that you do not seem to be one of those Jordan stans who, despite putting all their stock into who is doing the most on offence, spends all their time complaining about the offensive success we see in the NBA today. But unfortunately the lesson you seem to have taken from that evolution is that defence no longer matters, or possibly never even mattered that much, apparently out of some abstract sense that if a defending player did not visibly guard an opposing player with the ball, then they must have had no real effect in aiding any defensive stops which occurred.
