I do not agree that Crowder is at his peak.
If you look at the level he was at this time last year, and then look at where he is at now - the jump he has taken in such a short amount of time has been astronomical.
He surely has got to be in the discussion for most improved player of the year award. He probably wouldn't get it (I imagine Draymond Green has a lock on that) but surely he must be at the very top of the list of runners up.
When a guy who is 25 years old has made that type of jump he has in the space of a year, then I think it's very premature to declare him as "maxed out". He still seems to be improving as the season is going on.
I would take Crowder over Winslow myself, and it would be a no brainer for me. I think Winslow's upside pretty much is what Crowder is now, maybe (and that's a maybe) a tad higher. Crowder's most underrated 'talent' is his attitude / toughness. People tend to value physical attributes over mental ones in this league, but if you look at guys like Crowder, Smart and Draymond Green...they wouldn't be half the players they are without that attitude.
You could argue Smart's attitude hurts him.
I think of Smart as the NBA equivalent of a powerful but inexperienced sith apprentice.
He is very strong in the force (the force being represented by his will, motor and work ethic) but most of that force power comes from his passion and his emotion.
His raw force energy on it's own is enough to allow him to be quite powerful and effective, however for him to become a truly great sith he needs to learn how to make the most of that raw force energy by:
- Learning new techniques
- Refining existing techniques
- Working out how to control his raw passion / emotion, rather than allowing it to control him
These lessons can only be learnt with time and experience.
If he can learn those things, then he could become an extremely powerful Sith Lord (like Count Dooku). However if he can't learn those things then there is some risk that his passion may become his downfall, and he may end up getting cut in half by his opponent (like Darth Maul).
Either way, a Sith depends on their passion/emotion for their power. Take itway, and they are powerless.
I hope you enjoyed my little analogy
