I like Turner, and I was touting Lyles when no one knew who he was, therefore I'm not going to bad mouth either in order to build up WCS. But what I hate and despise is when people try and lump players into a box. A player is 22 years old, therefore he's already reached his max. Pure nonsense!!!!!!!!! Kareem Abdul-Jabbar was 22 years of age when he entered the NBA, do you think he didn't improve because of his age? Ray Allen - 21 yr's of age, Nate Archibald - 22 yr's of age, Charles Barkley - 21 yr's of age, Rick Barry - 21 yr's of age, Elgin Bayler - 24 yr's of age, Bill Bradley - 24 yr's of age, Larry Bird - 23 yr's of age. Now granted, all these players are HOF players, but they all improved once in the NBA? How about Steve Nash, who was 22 yr's of age and averaged 3.3 ppg his rookie year. Or John Stockton, who was 22 yr's of age and averaged 5.6 ppg his rookie year? My point isn't that WCS will become a HOF player, or even sniff the rare air of these players, but that you can't lock player into a box based on age.
I have no idea how good WCS will become, but I feel confident that he will become far better than he is today, and that's fine with me. The one big advantage that Willie has over Turner is his athleticism. Turner is a decent athlete, but is nowhere near the athlete that Willie is. he can't run the floor like Willie, which I think down the road will separate Willie from a lot of the bigs out there. Right now, at least from appearance, Turner seems to have better touch around the basket, and that's a hard thing to measure. Especially when Willie doesn't get many chances to show much of his offensive game. The bottom line is this, I don't give a damm whether Turner is great or not. This isn't a contest between Turner, a favorite of yours, and Willie. It isn't a zero sum game. Turner being good, doesn't make Willie bad, or vice versa.
By the way since you mentioned Ibaka, he turned 21 years of age two months after being drafted, and the biggest knock on him was that he had little or no offensive game, other than dunks, and lacked touch on his jumpshot. Also remember that Willie came to the game late, and was more known for his football skills in highschool. He didn't really take basketball seriously until his junior year of highschool. Players aren't robots. They don't all come with the same parts, and most of what separates them is between their ears. The smarter the player, and the more driven they are, the better they'll be, as long as they recognize their limitations.
