NBA 2K14

THIS IS NOT A SOLUTION, BROKEN ACHIEVEMENT WARNING
I just wanted to warn people that this achievement may have been broken with NBA2k14's latest patch. I've reach the required stats in blacktop mode 2v2, 3v3, 4v4 and 5v5. I also have reach the required stats in the park on 3v3 and 5v5. Still no achievement. If you look at the tracking for this achievement on this site, the last person to get it, did it on May 20th. The latest patch was released May 21st on Xbox one. And its not just here. Another achievement tracking site has the last person there unlocking it on May 18th. I contacted 2ksupport, but they claim that it should be working. If anyone has in fact gotten it after the latest patch, please share. Otherwise, newcomers beware. There's no telling if 2k will even release another update since the next game will be out fairly soon. :(

Since the other solution is pretty long I'll keep it short and simple. I got this achievement on my first try in a full court 3v3 game. I don't know if it's because I'm a point guard but I never had to inbound the ball so I got the ball a lot. Try driving to the hoop for both points and assists. If you get double teamed then pass to the open guy who will usually cut to the hoop. Games are to 21 so it shouldn't be that hard unless people are jacking up 3's (count for 2). Crash the defensive boards for the rebounds and make sure to run to the ball because we all know rebounding is messed up in this game. Make sure to get control the game so you either get an assist or point on almost every play and it shouldn't be that hard. I recommend getting familiar with my player mode so you know what you're doing. All in all it's really an easy achievement.

I was able to unlock this while working with a friend on the "Streak Buster" achievement.

This has to be done in the park online within MyCareer, and having a friend is highly suggested. We did a 2v2 match, with my friend and I being on opposite teams. If I was going for the achievement then my friend would try for bad 3pt shots in order for me to rebound them. The rebound part seemed to be most challenging overall. During the match you can try to drive the ball for your 7 points and keep passing for 3 assists.

You don't have to win the match for the achievement to pop. It will pop once the criteria is met. My friend and I basically coordinated on party chat, and let one of the other players know of our intentions. It's a very fast achievement.

U have to go into the park and do this can't be offline, I suggest getting a friend and helping eachother out for this one on either the 2 vs 2 courts or 3 vs 3 courts.
To get to the park you have to start a my career. On the plane or the car press B and go over to the menu option called the park.
Suggestions
Driving
Driving is your friend. Don't be afraid to posterize anyone. If you get a lane take it. More than likely the guy your against isn't a good blocker as many people aren't.
2vs2 Games
On the 2 vs 2s you can drive alot easier to put up your 7 points. Also you and your buddy could help eachother out for assists. They get open under the basket, pass it to them.
3vs3 Games
Points aren't as easy to score on this but the other two stats are easier. Since you have more people to pass it to assists become alot easier. Score your 7 points and then pass all the time. For rebounds I suggest just always crashing the boards. If your a big man on defense wait under the basket and get every rebound if your small just get in their as fast as you can and tell your buddies if you have them with you to do their best to box the other team out.
Fast-Breaks
An easy way to get an assist or dunk is to steal it and take the fast-break opportunity. After that make sure you fill the lane correctly. Have you on one side and your friend on the other not on two sides of the court but closer to the middle. If you want the point pass it to your buddy and right when your about to get to the hoop have him pass it to you and then just dunk or go for the easy layup. For the assist just do the same thing you take it down court then right before you get to hoop pass it to your buddy.

Hope this helped. Anyone looking for help or just want someone to play with on the park PM or add me as a friend and message me through there
Happy hunting(:
