90's basketball is very physical, now it has evolved because a team who have great 3-point shooters will likely win the championship. Look at Stephen Curry, if he is not good at 3-point shooting, he will not become a great player, and also now, big men are already shooting 3's, we have good 3-point shooters like Jokic which is a good example.
Yes, and I believe this is the trend! It's normal for players' styles to change over time, just look at what basketball was like 40, 50 or 60 years ago.
Nowadays, an important attribute is the 3-point shot, most players can shoot the 3-point shot (of course, some have a greater difficulty and others not so much).
There are also unicorn players, who are basically big players (maybe over 6"-11' (211cm) or 7" (213cm), they are fast, versatile, have good ball handling, can shot short range, medium and long shots. distance, and who currently play as SF, PF or rarely as SG.
Some of these examples are Durant, Antetokounmpo (even Kristaps Porzingis and Jokic I imagine could fit in that category)
One player who has just been drafted to the NBA (OKC) and who I see has great promise and is also a unicorn is Chet Holmgren! I even imagine he could be an improved version of Durant, let's see how he will performs in the NBA.
