Not sure how strong you are, but when I was playing professional basketball 8 years ago, a light squat day the day before or even on game day was helping me massively.
Saturday 3x5 Squat heavy, Tuesday 3x5 Squat lightday, Thursday 3x5 Squat heavy
or maybe just adjust the volume? Do 2x5 instead of 3x5? Especially for big muscle groups as the legs I'd assume that higher volume is only nessecary if you are an intermediate or above.
