I don't take credit for this method, nor video.
Watch this video, then continue reading.

Now, i did find this little bit.
Everyone has there own preferred method of play. Like, for me, it's 3 pointers. For you, it could be rebounds, defense, assist etc. I came to found mixing this video method, with my own little method. Will make you unstoppable.
Now, this is my opinion. So don't hate on me if it doesn't work for you.
Okay, so here is my method: Whatever play style you are. Pick a team with a majority of player(s) with that play style. For example. Rebounding, if that was my play style. I'd would preferably use the Knicks. With Melo, and Tyson Chandlers rebounds, you will own rebounds. Just apply the video method, and the players you prefer. Into positions fitting. For assist, use LA Clippers. Chris Paul And Blake Griffin. Are your big two.
For scoring, use Miami, Use the video lineup.
For defense, i prefer the Bulls, but also use the Thunder. I prefer the bulls because, i'm just used to there players. etc. But the Thunder will be easier.
There are thousand more. Just don't wanna write them all.
I hope this helped.
