You couldn't find more opposite player to compare. Araujo had no basketball fundamentals or IQ. Sabonis on the other hand has extremely good fundamentals and basketball IQ. He will struggle first year and will be just fine after that. Not like Zack Randolph was athletic freak yet he found a ways to be very effective.
Zach Randolph also has super long arms and was/is stronger than Sabonis will ever be. Certainly a more unique athlete than Sabonis I'd say.
