Your absolutely correct. Personally, I hate Iso basketball. I love ball and player movement. However, you have to have players on your team that can get you a basket when you need it. Having the ability to create and make shots, doesn't necessarily make you a ball stopper. The Warriors are loaded with players that can create and make their own shot, and yet they still have terrific ball movement. The reason is, they don't care who scores the basket as long as someone does.
If you can fill your team with highly skilled and unselfish players, you'll have yourself a contender. When you have a player like Tatum, who is only 19 years old, I don't think it's fair to lock him into a box. He's young enough to mold into the player you want him to be. He has never struck me as a selfish player. We have to remember, that to a large extent, he was Duke's go to guy. It's not fair to criticize him for doing what was asked of him
