I dont think you are in a position to say that its not hard to choose between those types of guys.
Why not? To my untrained eye, regardless of how old someone is, you take the guy who can actually play who also has the work ethic, motor, and intelligence to succeed, as opposed to drafting a guy because he has better measurables, etc., imo. I just don't think that you should ever draft someone hoping that they'll learn how to dribble or work hard, especially because you can't teach the latter. The guy is either a hard worker or he's not. Case in point - James Young vs Rodney Hood. Sure, Young might have better measurables, but he can't even dribble and there's simply nothing upstairs with him; and yet, despite having more information on the two than fans are privy to, Ainge takes the guy who doesn't work hard and dogs it on the court
. Huh?
Ainge has a long history of taking the "hard-working" "high motor", "safe" kind of pick. If you wanna nitpick Ainge's drafting skills (Which you LOVE to do with 20-20 Hindsight, as if your supposed to hit on every single pick), I don't think trying to say that he doesn't pick hard working guys is it. In the past few years he's taken:
Bradley, Sullinger, Melo, Olynyk, Smart, Young, Rozier, Hunter and Mickey.
Bradley, Olynyk, Smart, Rozier, Hunter and Mickey are all guys that had unquestioned drive and were/are considered hard working. That's 6 out of 9 guys.
Look, you can't make "motor" or "work ethic" the only thing you base draft decisions on. Some guys have questioned motors and work ethics that come around. Some guys are very valuable without strong work ethics. Sometimes you have to take guys you consider to be "projects". Guys you have to teach to become NBA caliber players. Guys who have unrealized potential that you want to extract. Not every guy can be a Marcus Smart as far as mindset goes.
It's crazy. Ainge takes a guy like Olynyk and people say "Jesus, why does he always have to take the "safe" pick, the "high-motor" guy, he has to swing for the fences!". Then he takes a guy like James Young and you say "Why would Ainge take these multi-year project guys with questionable work ethics! How hard is it to take a guy who "works hard?!"".
When you draft outside of the top 3-5 guys, you have to be open to taking all kinds of players. Your NOT going to hit on every single pick. I swear it's almost like you expect Ainge to draft a star player every time, no matter if it's the 3rd pick or the 30th.
