After an up-and-down ride last season, the kid they call ‘Zeus' is looking for more as a sophomore.
"I worked on a lot this summer," Tarczewski said. "I felt I had a lot of improvement to do. I really worked on my post moves and footwork.
"And then I worked on my jump shot, maybe a little pick-and-pop or something like that. I think having more of a jump shot will only make things easier down low."
Tarczewski anchors what may be the best front court in the nation. Alongside fellow sophomore Brandon Ashley and freshmen forwards Aaron Gordon and Rondae Hollis-Jefferson, teams are going to have nightmares trying to protect the paint against Arizona.
After working diligently in the weight room throughout the summer, the seven-footer is much leaner than he was this time a year ago.
Don't mistake a slimmer frame for a lack of strength, though.
"Kaleb's gotten stronger, and I think he's gotten more agile, as well," Ashley said. "His mid-range shot is a lot better, plus he's really fine-tuned a lot of his post moves this year."
With more teams taking out the prototypical five-man from their rotation, Tarczewski will have to make adjustments every time Arizona takes the floor.
One night he could be matched up with a seven-footer who likes to throw his weight around and live in the paint. The next night, he could have a major size advantage on a quicker, more athletic 6'8 swing-forward.
Regardless of who he's matched up with, the Wildcats would be wise to get Tarczewski the ball around the rim.
"When we play 5-on-5, he's almost unstoppable," Gabe York said.
