I think what stands out about Buddy and reminds people of James Harden is the way he processes the game and reacts to the defense.
Hield seems to be playing the game in slow motion. He's going at one pace and everyone else is going through the motions. There's a fluidity to his athleticism that highlights his IQ and anticipation.
The great players have this 'slow mo' aura about them and to me, Buddy is one of those guys.
He's only just started to bloom aswell. His rise has been so quick and when you combine his confidence, shooting ability and IQ with a truly hall of fame work ethic you have a recipe for something that has a good shot at becoming great.
People say he's reached his ceiling but to me he's only just scratched the surface. Why can't he keep getting better? Because he's 22? That's bogus to me.
I think the huge difference is James Harden already had great ball handling in college, great court vision, whereas Hield has slowly started to have slightly above average handles. I'm not that impressed with Hield. I don't think Hield is going to be able to break down the defenses like he once did in NCAA, compared to the NBA.
But I will say Hield eerily reminds me of Harden, just based on how they play that 'slow mo,' type of style as you mentioned. But how much better can he get? His height isn't going to get any bigger, doesn't jump out athletically, while his defense still needs plenty of work.
I'm just hoping that if we pick Hield, its because he was the BPA. I'm not 100% convinced Hield will be this great of a shooter/scorer, due to his sudden rise in stock by one great year. If Hield had done this for more than one year, I would surely be more okay with taking him, but there are many issues or concerns in my book.
Also people are mentioning how similar he is to JJ Reddick, but I digress. Hield has better handles, and I think he'll be a far more competent offensive scorer, rather than a catch and shoot through ball screen type of player that Reddick is well known for.
Hield doesn't really have a better handle though. He's just a better athlete. But it won't matter in the NBA.
Thinking Hield will be more than a very good role player is flawed thinking.
Same thing people said about Curry and Kawhi 
Wasn't Curry a #7 overall selection? Terrible ankles, slight build, nonexistent defender, one-trick pony who may struggle against truly elite talent coming from small school. Little potential as a PG/creator and at best, a high-level role player eventually in the NBA. Ha, ha, ha! None of these young lads are Michael Jordan coming out of college, but a few will take quantum leaps in their development at some point, which is what all franchises hope for from their draftees.
High-character guys with suberp work-ethic demonstrated by season-to-season improvements on weaknesses in their skill sets may often prove to be wiser investments than more physically gifted (and younger) prospects with different mindsets.
No one. No one, and I mean, no one; could've predicted that Curry would be this good.
As for the bolded part, I definitely agree. I love hard working and hustle players, but 9 times out of 10, if you got a player that has a mix of both, with physical gifts, a smart but troubled mindset, (like Rajon Rondo,) I'll take that player over the hustle on both ends, and hard working player any time of the day.
You can't teach ethic and hard work, but being physically gifted can help make up for most deficiencies.
