No, you have to win and reach a certain number of MT to get 1-3 stars, with the requirement for 3 being slightly more difficult than the requirement for 1.So in theory you could beat Domination in 33 games.
I wish there was, but there isn't, unfortunately.
On topic: L2 cheese is the easiest way to get lots of MT this year. You wanna tap L2 before shooting from anywhere in the paint, this gives you an extra 5 MT for post move score. That works even on fastbreaks. I'm running a 3-2 extended with Aldridge and DeAndre. Just PnR it with either of those guys and let them go to work. LMA is fantastic because he's a great shooter with a quick release, I obviously have him pop most of the time while DJ is the roll man. Even if I have an open lob to DeAndre I just pass it to him and tap L2 for the extra 5 points. Also helps me getting the 10 FTs easily, which is something I otherwise struggle with.
