Your certainly entitled to your opinion, and I can't tell you that I think Willie will be a star. To be honest, I don't know what Willie will eventually be. I can tell your what I hope he'll be, and what i think he's capable of, but that's about it. I try not to talk in absolutes because the truth is, I don't know, you don't know, and I doubt that even Willie knows at this moment. However, having watched NBA basketball for over 50 years, what I'm seeing from Willie isn't a surprise, and if he does take a huge leap forward this season, that wouldn't be a surprise either.
Basketball aside, Willie has reached that age in his life, where a person starts to become completely mature. The average male's body tends to mature ahead of his brain, and at around age 25 his brain starts to catch up with his body. At age 25 most men become more introspective and start to question themselves as to what their goals in life are. So its not a surprise that many athletes tend to reach their peak around that age. Of course it is an individual thing that comes with no guarantee's. I guess we'll see!
Yeah I realize that there are exceptions and players that become stars or seemingly reach their peak earlier, but most of those players had been playing the game since they were kids. They grew up loving the game of basketball. Willie didn't start to really play the game until his junior year of highschool, so he didn't arrive with the same foundation as they did. Hopefully he's finally found that love of the game. I know I would have played baseball for nothing because I loved playing the game. The money wouldn't have been rejected though.
