I'm not talking about starting fist fights with guys. I'm talking about playing soft. I think if somebody gets physical with Olynyk, they can make him utterly disappear. The guys you mention above are not soft players, although in his earlier years, I think Dirk, too, used to shy away from contact probably too often. Kelly has way too much Brad Lohaus in his game. You like him, that's fine. I'd sooner move on from him, despite him having some skill. Ultimately, we'll probably get an upgrade at PF and keep one of Sully or Kelly. I'll take Sully (though I have issues with his weight problems, but who doesn't.) Given the choice between Sully's weight problem and Kelly's low-T problem, I'll take Sully.
That's a fair argument, and we each have our individual preferences, but big difference I see in those two guys is that Olynyk is showing clear improvement as an overall player, while Sully (IMHO) is not.
Sully's best offensive season was probably his rookie year, where he shot 67% inside the paint, had a half respectable free throw rate of 0.28 and shot 49% from the field. This season he shot only 62% in the paint, had a woeful free throw rate of 0.18, and shot 44% from the field. All of this tells me that he's getting lazy, which is leading to him settling for lots of jumpers and not bothering to try and get easy points.
Defense is harder to measure, but we can use Defensive Real-Plus-Minus as an indicator. Last season Sully ranked 23rd among NBA Power forwards (+1.58) while this year he ranked 53rd (+0.16).
These numbers indicate to me that despite his high skill level and relative youth, Sully isn't actually getting better - if anything he's just getting lazier and lazier.
By comparison Kelly Olynyk (despite being a more perimeter oriented big) has improved his FG% in the paint (from 65% to 68%), has slightly improved his Free throw rate (24.3% to 25.8%) and slightly improved his FG% (46.6% to 47.5%).
Defensively Olynyk made huge leaps, with his Defensive RPM jumping from -1.71 (62nd among centers) last season to +1.71 (23rd among centers) this season. That's a huge jump, gong from being the 4th worst defensive center in the NBA, to being at least a starting caliber defensive player.
Also given Olynyk's lack of physical potential (short wingspan, lack of strength, etc) for his position I think that makes his improvements all the more impressive - it means he's making these improvements simply by working tirelessly on his game.
Sully at least has some physical potential thanks to his strength and decent wingspan - if he got in shape, he could have a physical advantage against his opponents on some nights. It's easier for a guy like that to improve as a player, but Sully has only dropped off.
I respect this about Olynyk, and if the current trends continue over the next few years Olynyk will slowly (but steadily) improve in to a solid starter, while Sully will quickly build a reputation as the lazy guy who just doesn't care, and become that next talented big man that no team will sign.
As much as people might label Olynyk 'soft' for his personality and his finesse game, it seems pretty clear to me that there is absolutely nothing soft about his work ethic and his desire to get better as a player. I also see nothing soft about a guy who cops a giant black eye, then goes on to score ~20 points and lead his team to victory.
On the contrary I look at Sully as being soft because he lacks the mental strength and focus to keep motivated, keep his head in the game, and put in the effort it takes to constantly improve at this level.
I do get where you're coming from because Sully has the physical size to absorb physical impacts and power through, while Olynyk is physically more frail an easier to push off his spots, etc. But in terms of mental strength - I've seen Olynyk take a LOT of abuse/bumping/bruising in the post and I don't know that I've ever seen him complain about it. He also seems like one of the most willing guys on this team to slide over and take a charge.
I think KO is certainly not a mean guy or a thug (despite what Kevin Love would have you believe), but I wouldn't say he's soft either. From what I've seen he's got no problem at all sacrificing his body for his team.
Albeit, each to their own!
