How to unlock the Wrecking Crew achievement in NBA JAM - Definitive Guide
From the game menu :
game mode
remix modes
smash
Get the ball and dunk. steal the ball from the other team and keep repeating till you break your back board
From the main menu> game modes> remix modes> smash. It easier to use three controllers (Player 1 team is User/CPU and Player 2 team is User/User) to ensure your team, Player 1's team, wins the game in under 2 minutes. Using three controllers, have player 1's team go for alley oops (alley oops destroy the backboard quicker) and when Player 2's team has the ball, steal the ball and go for another alley oop. This should take no more than a minute to a minute and a half.
The easiest way to get an alley oop is to have your CPU teammate throw you an alley oop by pressing up on the and hitting to have your CPU teammate pass you the ball in mid air to complete the alley oop.
You can obtain this one fairly easy if you play against a team with low dunk scores on remix mode. You can also just use the Play Now method (See Clean Sheet) except in Remix modes. I picked it up the first time I played a Smash match in the remix tour, just remember alley oops and dunks when you are on fire do the most damage.
