Most of the time great players are great based on mentality, Jalen could take over games right now with the right mindset. But I agree, he's only 20 and his game will develop over the years. Sometimes fans aren't used to seeing a young player or team realistically develop over the long term.
Have I mentioned how much I hate the Jazz ?? It seems like its a requirement that they have multiple guys that you would love to punch in the face.
