Nope, calves are like 10% of a jump if that, they are important, but not that big a deal.
jumping and bouncing on the toes is speed work for your calves
Don't bother breaking down the jump and isolating parts, jumping doens't work like that.
How I would split it up off the top of my head -
1) eccentric strength and reversal speed in the dip and absorbing energy when you dip to jump from motion - depth jumps and alttitude drops
2) concentric explosion - oly lifts, jumpsquats, speed squats, weighted ground based plyos, overhead medball throws
3) general strength - squats, deadlifts, pulls, good mornings etc
4) core strength - abs and lower back
5) arm swing power + intergration - pushpresses, incline presses, pull through dumbell swings, overhead medball throws and so on
6) achilles tendon elasticty - ankle jumps as per above
7) skill/technique - jumping
doing plyos on your toes, olys amd pulls, speed squats and GMs/RDLs onto toes etc as you should is enough for the calf strength and power
