Here's the best way to do this:
First things first, set your games to 12min quarters and the sim games to 1min quarters (that way, the other teams only play 1 minute games and players like Kobe will only get 2 points per game) and you will have plenty of time to rack up stats with 12min quarters. Set the difficulty to its lowest possibility (i think its Pro).
Make sure you are on a bad team. If you get drafted by a good team, request a trade to a bad team(s) with a player that has a low rating at YOUR position. That way, once you're traded, you will be starting (on a bad team) sooner rather than later (depending on your Overall rating). And by bad team, i mean BAD. You don't want to be on the Lakers because then Kobe will rack up good stats and steal your MVP!!
If you are not a starter right away, I would recommend playing some games so you can get good xp to up your overall rating (offensive and defensive awareness are good ones to up).
Once you're a starter (or are getting alot of minutes (30+ is a good number)--see My Player --> My Minutes) you really dont need to play the games anymore. Just start up a game, press start, press quit, and press sim to end of game. Do this over and over again until the season ends. You should get MVP by season's end.
WARNING. THIS IS VERY IMPORTANT: Make sure you ALWAYS have autosave OFF. That way, if your player ever gets injured, you can quit out of My Player and re-load. I say this because if you miss too many games, you will not get MVP no matter how godly your stats are.
NOTE: This solution will also help you with getting Rookie of the Year and selected as an All-Star. HOWEVER, simming games does NOT give you xp, so your players overall rating will not increase unless you use xp from milestones. SO, if you are also going for the 80 overall rating achievement, I recommend you play games until you get that 80 overall. Once you get better you won't need to play on 12min quarters.
Also, in the post-game interviews, answering with arrogance will almost always increase your league-wide popularity, which probably (not 100% sure) will help your chances at getting MVP. For those of us who follow the NBA, we know that the MVP pretty much comes down to stats and a popularity contest.
If this solution has confused you, or you do not understand, please comment/pm me/message me on xbl before you vote this negative and I will try and help you understand.
My situation: I am a few games past the all-star break. I am a PG (the easiest and funnest position in my opinion) and am a 71 overall. I am on the Kings (lol) and we are in 2nd place in the conference because I am awesome at this game (hehe). I lead in the Rookie of the Year race, but NOT the MVP race because I made the mistake of saving after an injury that caused me to miss 20 games. I'm HOPING that by season's end, that I will have played enough games to be considered. DO NOT MAKE THE SAME MISTAKE I DID!!
