You can get all the achievements in one game, just do this...
1. turn your sliders all the way up & the cpu all the way down
2. turn all the foul calls off (shooting, reach-in, charging, etc)
3. turn the cpu tendencies to drive 100%
4. set half length anywhere from 7-10 mins
Now the trick to get 45 rebs is too shoot from half court and when you miss get the rebound and do it again and again til you get the 45...congrats your done
now go play a real game...lol
