Recently, before reading this, I've done Kobe's 81 and 100 points achievements it took me 2 and a half quarter (12 minutes each) on rookie . I've also done the Kings vs Lakers on superstar achievement. Just selected 2 minute quarters, and beaten the Lakers - easy...

.
I think that the hardest achievement is the D-Wade buzzer beater in 2 OT, I think that the easiest way to do this is to play 2 minute quarters on rookie and let opponent score and manage the result of the game to make it tie in the end of 4th quarter and of the first overtime(maybe by switching sides during the game) . Then score a buzzer beating shot in 2ot by the flash.
Andrew, I've seen that you won the championship in your dynasty, have you played all the games or simulated some, If you didnt simulate I wonder how have you managed to play 82 games + playoffs since October , 2 minute quarters or what ?!

I've also seen that you havent made the triple double achievement

What are you waiting for, just grab those 10 rebounds with Derrick Rose and you are practically done. I made my with Howard - 30pts, 10rebs, 11as ( 8 minute quarters - superstar lvl)
