No one is trolling when they assert that 80's/90's Jordan would completely destroy today's NBA (given the rules that heavily favor the Offense, all the Bigs on the perimeter chucking 3's -leaving the paint/rim WIDE OPEN- and with the Defense being so soft and weak relative to the 90's).
OTOH claiming 50's/60's Russell would still be the GOAT (lol) and the best Defensive player in the game today is clearly trolling because the game today is much like it was when Bill played: Super fast paced, free-flowing, high scoring Offenses, minimal Defense, minimal Contact, etc.).
Thus, given that today's players are sooooo much bigger, better, stronger, faster, more athletic, more skilled and more talented than the players from Russ' Era, Bill would be lucky to make an NBA roster today.
This, of course, is a conclusion we can all agree on based on the BWGC logic...
