Analytics didn't kill variety in the NBA. Rule changes to favor the offense have killed variety in the NBA.
Reinstate hand checking and the 3 point statistical advantage declines dramatically. Drives to the rim become significantly harder.
Remove the 3s defensive rule and the value of great post up and rim defense goes way up.
Reinstate 2 hands on the opponent and you'll see more variety in offenses and more use of sets to break players free, AND more creativity on the part of the "isolation" players.
The rise of the 3 and lay up game isn't the fault of analytics. The rise of the 3 and lay up game is because they made it TOO EASY to score them by taking away the tools of defense.
When a post up player can't even back down an opponent without getting an offensive foul, when even a light brush on a jump shooter is a foul, when points are being given to the other team on ticky tack fouls due to a fear of contact, THAT's when it became obvious that driving and 3 pointers were the *easiest* way to put points on the board.
Even just bringing back hand checking would *dramatically* change the game. And for the better in my opinion.
J.R. Smith: "They were pretty much scoring at will. Especially my guy. I don't know what the hell I was doing on defense."
Raymond Felton : "The play was give the ball to Melo."
