Nobody plays defense anymore? More like the rules make it harder to play defense, and there is just way more talent in the league than ever before. Big men alone in today's league have so much talent and different skill set that is ridiculous. Andre Drummond, Clint Capela, Dwight Howard, Rudy Gobert, Nikola Jokic, Demarcus Cousins, LMA, Anthony Davis, KAT, Blake Griffin, Deandre Jordan, Marc Gasol, Kevin Love, Joel Embiid, Steven Adams, Porzingis, Horford, Whiteside, Kanter, etc.
Russell is great, and has great stats sure, but you are literally comparing a time with 10 teams in the league, where the Celtics were beyond stacked with hall of famers, to a league where there is 30 teams, with much more talent and a changed game. Bill Russells lack of offensive talent would be taken advantage of in todays game. There is a reason someone like Ben Wallace wasn't a star.Bill
This is why comparing these eras is nearly impossible and pretty pointless. You will never convince me that Bill Russell and his mid 40's shooting %'s are the greatest player of all time, and I'm not going to convince you Duncan, Shaq and etc are better.
