k i dont get it. at first saying i should do more plyos now all i need is six months of them.
i think you should do more plyos, and at 16 or 17 you could use a few years of doing this in the off season under your belt. Heavy squats are gonna help too, however IMO if you start putting on too much bodywieght, even muscle you are gonna lose inches on your vertical.
Now, I don't know your body type, etc. My point is if you are say 6' 180, and doing plyos, you are gonna have more jumping ability than if you are doing just heavy squats putting on more bodywieght. But, at your age, both movements would be beneficial. I would just focus more on plyos if your goal is to increase your vertical.
also, when you are doing squats, try to do them as explosively as possible. Squat down at a normal rate, and then explode up as quickly as possible. Some basketball players even do jump squats with a light barbell....although, I've never tried them.
cleans and clean and jerks are also awesome for overall exposive strength, and they are similar to the movement of going up to the rim two handed.
