That kid in middle school, or high school, or even in my early 20s playing pick up games at parks.
But everyone has played against him. Might of been in rec leagues, school, pick up games. He's that dude with less physical flare and natural talent, kinda step below the rest. Yet he throws you and your teammates off track. Out hustling everyone, and doing all the fundamentals one was taught when they were 6-7 years old. Move your feet side to side, stay on front of your man, keep your arms up and out, swing your arms up and down, keep active.
Now I realize, yes he's in the NBA, yes he's better THan me. What I'm saying is if it was Irving on Curry. They both have such smoothness, that they would just try one up each other. But Dellavedova is that guy that is non stop all up on you, constantly bumping you, flailing his arms. you're thinking to yourself " damn, psycho, chill out!"
Regardless of anyone and their friends skills on the court. Everyone has played against a Dellavedova on the court. The guy everyone is scratching their head and going "WTF!?".
