You can practice and work on your ball handling and shooting because you might not be big forever and might end up as a guard. So work on shooting and work on ball handling
"I've missed more than 9,000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."-Michael Jordan
