I'm actually very happy with this pick now. Reading behind the lines, I think the Olynyk pick gives away Ainge's vision for the team right now.
Note how Ainge stresses multiple times than Olynyk is a COMPLEMENTARY player. He says he likes athletic guys, and guys with high potential, but in the end he liked Olynyk because he's NBA-READY.
Look at Ainge's draft history. There's no doubt that if he can gamble on an athletic guy with lots of potential, he will. Honestly, most of Ainge's busts fit that mold exactly. It's very telling to me that instead of getting someone like Shabazz or Giannis, he goes out and gets Olynyk, even MOVING UP so that he could acquire him.
Ainge is collecting assets, but he's not looking to compete again in 5 years or so. He's looking to get right back into the mix now. All those assets are going to come into play so we can make the next KG/Allen trade. For everybody who loves draft picks because they net teams very affordable contributors on the rookie deal, Olynyk is that guy.
It might not be this very next year, but the C's are rolling out a contender soon. Ainge is going to bring in solid guys via trade and free agency, and Olynyk will be right there to COMPLEMENT them because he's NBA-READY.
