Tyrus Thomas and Adam Morrison were top 5 picks in the same draft. Aside from ESPN's hype machine - who in the draft are you so sold on that is such a can't miss piece to a championship puzzle that we should've tanked the whole season to have a chance to maybe be in position to take them (if the lotto worked out in our favor?)?
I'll be kind enough to answer your question, if you'll do mine.
I think out of the top 3 (Wiggins/Embiid/Parker) at least 2 will turn into cornerstones for a franchise. I also think out of the rest there are likely to be 2-3 more who will be all-star level. I think it will be a very good draft. Am I certain of it? Nope. GM's get fired on a regular basis because there are no guarantees. You seem to know it all though based of playing in gyms in front of parents of players and maybe an aunt or girl friend or two.
Now me. Do you know more about basketball at the NBA level than Dennis Lindsay? What about Danny Ainge? Simple question.
