When I saw the thread title, my first thought was -- no brainer -- take #17. After reading most of the posts I am even more convinced.
Lakers, Celtics, Heat, Spurs, Pistons, Bulls, Rockets make up the winners of the last 19 champioships (I could go further to the same end). Name the team led by a young core? The only team you could make an argument that won with a young player as its best player would be Miami in 2006 -- but that's arguable since they happened to also have the most dominant center of the era.
Look at the years it's taken for Orlando, Cleveland, Atlanta to develop. And those are the teams have gotten somewhere. Now look at the teams who've had young talent and who've had false starts and look pretty mediocre now -- Charlotte,OK, Bulls, Wiz, Portland.... It's REALLY hard to throw a team together around a good 19 year old and expect a championship.
I think it would be interesting and we'd be hopeful, but 5 years from now there's a good chance we'd still be waiting.
I like #17 just the way it happened.
