You think he'll live up to his 2nd overall pick expectations?
Thats not a bust that's changing the goal posts.
Right now he is good enough to start in the NBA on a winning team and is productive on the floor. A bust is Markelle Fultz. Someone so bad it hurts you to keep them on the floor. Fultz was legit the worst player on the Sixers this year and forget starter, he was not even good enough to be a bench player. When you remember that he was the first pick and that they traded up to get there that is a boat sinking type of catastrophe.
Now if you want to move the goal posts to whether Lonzo is going to be an All Star? That is a fair question and unless he figures out how to be more productive on offense (definitely attainable for a guy as smart as him but not even close to a given) thats a stretch at the moment. I think it is fair to want to get an all star from a 2nd pick, but that is less common than you might think. Its hard to make the all star team in the NBA and it is really hard to make it consistently.
For Lonzo to get there he has to make a jump but you are crazy if you are giving up on him already. He was not ready to start last year and has become kind of legit after just one season. You have to give the kid at least 1-2 more years to see what he is going to be.
I think it is more reasonable to be disappointed in Brandon Ingram. We are in year 3 and everyone was hoping to see a bigger leap than we got. But at the same time to be fair he is only like 21 or 22 years old. This shit can take time sometimes.
