there are excersises that have worked miracles for guys with lousy vertical,hayward added 6inches to vertical and 15lbs-there are drills for lateral---you could see improvement over summer and i think his vertical has progressed-zeller and KO both have upside--they both have basketball roots-i think kelly is still adjusting to the number of games--sully sure can rumble for a big guy-
A lot of those programs, are all hype to sell you stuff. If it is so easy, why can't everyone jump? Most of the sites espousing this training is trying to sell you their program or a product. I will post some of the science below. A person would be better off using the BFS (Bigger Faster Stronger) weight program that what you mention. It takes hard work, you make it sound like any Joe Blow can do it. I don't see that I think it takes hard work and dedication but I do not see that happening with Jared. I wish it would though.
Hayward is a lean body type and more predisposed to be faster and jump higher because he is leaner. He also has a work ethic, something we have not seen in Sully. How has his body changed since in the league? I see some change in Oly. Zeller is already a decent conditioned athlete. Yes, people can improve with hard work, but it is hard. Looking at Sully's body type, do you think he works out hard a lot? The guy is gasping for air in games.
You are born with so many fast twitch fiber. It is easier to increase the slow than the fast. The fast is where speed and power lies while the slow is endurance. You can improve both. But most people including Sully do not lift 75% of their max weight to build that power. It is hard work and most people dread it. In fact, his workouts on the internet were a joke that I seen. Muscle Adaptation requires stress, I do not always see that kind of effort from Jared.
https://www.youtube.com/watch?v=L3Aj4D1L86shttp://sportsmedicine.about.com/od/anatomyandphysiology/a/MuscleFiberType.htmhere is an example of training improvement of fast twitch.
http://www.ncbi.nlm.nih.gov/pubmed/2150579Scientific study on fast twitch training, it increased 6% in six weeks. That is changing the composition of fiber types only. That means more power but won't always translate into better leaping as your are working what you have to work with. Sully will not do this kind of workout it is not in his nature. Sully moves slow, he is not even a remotely fast twitch guy and he is lazy. How often to you see him walk to the sidelines or sprint up the court. He does not sprint in the games let alone in the off season. He is young, he could do this but I do not think he takes it serious.
Muscle strength is related to the cross-sectional area of the muscle. However, this strong relationship diminishes when "explosive athletes" and endurance athletes are compared. What most studies suggest is that strength is highly related to muscle size. However, people who have a disproportionate amount of fast-twitch fibers will gain strength faster than those who do not. Fast-twitch fibers tend to be stronger than other fiber types, so people who have more of them will tend to be stronger and have greater potential for strength gains.
Several studies have shown that fiber composition is genetically determined. Genetic researchers often investigate the influence of heritability on a trait by studying monozygotic and dizygotic twins (identical and nonidentical twins). Fiber distribution and muscle enzyme activity in monozygotic twins is almost identical in most of these studies.
Genetics is not the sole determinant of individual differences in strength. Numerous studies have shown that many successful strength-speed athletes do not have a predominance of fast-twitch motor units in critical muscles. Further, in athletic subjects, fiber composition is only marginally related to the time subjects can maintain isometric force and perform explosive squat jumps. Genetics exert a strong influence on the ability to gain strength. A good training program can make up for "genetic deficiencies."
Applying Basic Principles of Exercise Training
Trouble is that training result will be finite and you have to do them. This science based not trying to sell you jumpsoles or air alert or the like or a miracle testerone booster or elastic hands, though those can probably help an underdeveloped guy some.
I think Weight Lifting is the best way, sprinting and polymetrics. Ever notice how many jumpers are well developed. A lot of them of mesomorph body type.

Let's hope it happens, but I think nature and willpower is against one of our player. I think KO has changed his body some and continues to work on it. Zeller seems dedicated. Everyone knows my low opinion of Sullinger's effort level.
