First off i think the season the Cs dont take him is he simply wont be there, he is going to go alot higher then alot of the experts expect.
In 2001 kwame brown was the #1 pick in the draft, if the nba didnt have an age min, then last year Tyler would have been finishing up his senior year of high school and would have been a top 10 maybe top 5 pick. Instead of a dominate senior year and then being picked out of high school he was placed on a differnt path. NBA teams will still look at his potential and someone will take him top 15.
Tyler has shown playing over seas that he is not going to be a dominate scorer in the nba, however I see Tyler having the potential to be a solid nba center 12pt 8rb 1.5 block type of player (if developed correctly)
Actually, if there wasn't an age minimum, he would have come out after his junior year in highschool, and who knows where he would have been picked (probably late first round at best).
However, if they were going by the old age limit (highschool graduating class), he probably would have gone in the second round to undrafted in last years draft, because he was coming off a nightmare of a lost season, as he skipped his senior year of highschool, went to Europe, and didn't even finish the season after barely playing.
Someone may have taken a flyer on him in the second round, but no one would have used a first rounder on him, after that disaster of a season, and all the questions over the decision he made in general.
