Running the style of defense you do, you could probably put up very similar numbers by putting the controller down before the play, standing up, doing 10 jumping jacks, and resuming control.
It isn't you, its the game. The game does not know how to react against that play because it is a known glitch. It is a money play. If you run it, it will work with a high success rate.
So if you are going to come on here and complain about it, people are going to tell you the honest truth, that you are running a money play that is going to work every time and rather than complain about the game, run a different defense.
If you want better results:
1 - Get a good pair of sliders. Playing on base difficulty means you are playing a very broken game. Sliders can't fix it all but they fix a lot of it and make the games a ton more fun because of a bump in difficulty that doesn't make the game ridiculous. Use someones completed set, not something you half-*** threw together, and then read point B.
2 - Don't nano-blitz. What you do on defense is actually banned in many competitive tournaments around the country because it is simply abusing poor game mechanics. No set of sliders can fix this. Your results will be the same and therefore makes sliders null.
