Are you nuts? You can get a jump shot in 4 years in college, you can't gain a ridiculous leap or speed if you don't have the kind of physiology to allow for such athleticism in the first place.
You may adapt a better handle, but you're not going to become that much quicker in terms of lateral quickness.
Some people have talents that others don't. Cashmere Wright is never going to be a tall point guard, Sean Kilpatrick is never going to leap over a 7' footer, at the full extension of his jump shot, at the height of his jump and block it. It's not physically possible.
Likewise, Gelawn Guyn isn't going to have the same vision as Dixon being like 3 inches shorter. He isn't going to grow longer arms, be as fast, post up and it's going to take him years, before he has the kind of skills with his handle, to create his own shot. That's just reality my friend.
What on God's earth are you talking about? Are you suggesting people don't play their best as upperclassmen? Do you watch basketball?
Hardly. You have to use context. His shooting suffered, because he was being hacked! Also because he had to shoot more, the more you shoot, the more you'll miss. People get tired when they work harder over the course of a game. His role and his minutes and the amount of contact he took changed. His average from the floor only dropped slightly.
Again context.
Okay, apparently getting hacked doesn't affect your shot LOL
Why don't we do an experiment? You go take 10 lay ups and then I'll come in, have you take 10 more and foul you as you're going to the basket.
Do you think it'll affect your percentage?
Context... Like I said. You can't just look at a number and expect to know the full story behind it.
