Training for Throwing Shot Put, Matt Vincent Info?

Hey, I have been helping a very talented kid lift for about two years now. He competes in throwing and this year as a junior went to state for shot put and threw 53’ flat. his strength is very good (Bench 315x3 squat 405x6-barefoot DL 455x5 I have watched him recently do all these with reps left in the tank)

I know if its broke dont fix it but i was wondering if anyone has any experience with matt vincents training books I have only trained the kid for strength but was thinking now maybe he could get a little more sport specific even during the off season.
