Don't be so nervous, man. Look, essentially you want to raise SLIMM's scale, you can choose to raise certain areas of things you feel you are not seeing enough of by editing shooting sliders.
Or you could raise Slimm's entire scale manually for the player you want to shoot more.
And if you want to be part of a test as of right now, lower fast break to 0 and let me know if your still having the problem of Peyton to Harrison
