Winslow was an Ainge binky more than a consensus talent. If you believe all of the rumors, Ainge was willing to go up pretty high to get him, but he dropped to 10.
People trying to talk themselves into selecting someone other than Fultz with the #1 are a little crazy. It was fine to talk about that stuff in an effort to get your mind around not getting the #1 pick, but he's really a different level of talent than the other guys. Ball maybe you could also consider because he's so unique (if you count BBIQ as a skill, he does have the biggest gap in any single skill from any of the other guys, I think) and you believe his shot will carry over to the NBA (I don't, but others smarter than me both agree and disagree). Jackson or Tatum you can call "Ainge guys" all you want, I don't think there is any scenario where drafting them ahead of Fultz makes sense (of course, if you trade down in order to get other assets, then maybe you can have it make sense. But talking yourself into drafting Jackson or Tatum #1 seems pretty foolish.
Kyrie seems pretty overrated generally. It's really hard to tell his true talent because LeBron does the lion's share of his job, which frees him to only initiate when he has a mismatch, to get open looks, to not really have to care so much about defense, etc. To be fair, of course, if Fultz is as good as Kyrie he'll be a successful pick.
