What you're saying is fair but I read it as basically "Portis is unproven. No one knows if he's going to be good." And yes, that would be correct. However, part of being a fan of basketball is projecting young players, identifying their strengths and weaknesses, and analyzing their skill sets. I'm not saying Bobby is going to be a 5x all-star, but he's going to be a very, very good player and I wouldn't count out all-star appearances for him. Whereas Niko, I would be shocked if he ever made one.
I was never as high on Niko than a lot of other people. I certainly never saw him anywhere near a Dirk Nowitzki. The thing that troubles me about Niko is when I look at his game, I don't see one dominant or eye popping skill set. He shoots a decent percentage, is a respectable rebounder, decent defender, ok ball handler, not a great driver with the ball, and relatively soft. I just don't see anything he does very well. He's pretty good at a lot of things, and lacks that one "strength" you want to see.
As far as Snell goes, he never really "dominated" pre-season and he's another guy that just didn't jump out at you. He was always a spot up shooter with a decent ability to put the ball down, but lacks the fortitude. In short, I never saw anything from Tony Snell to get me overly excited. Your point is basically "Bobby is unproven and other guys have been a let down after fans were high on them." To that, I can't argue. I could only explain why I'm high on him and the rest will take care of itself.
