During his Freshman year, Zach's physical traits really jumped out. He had a great arm and consistently showed his athleticism with his ability to run around. The question was simply whether he'd be able to become a quality decision-maker in order to take the offense to another level. It took a year of battling injuries and a full offseason for him to get there, but once he did his draft profile absolutely skyrocketed.
I view Caleb similarly. He had a slow start out of the gates but his strength and athleticism were never a question. Almost immediately he squashed any concerns about his ability to defend multiple positions and even proved himself as an exceptional rebounder & effort player. His highly anticipated shooting did not show up initially, but now that he's finding his stroke his game has risen to another level. He will be valued as a 3&D prospect and stretch 4, but if he can develop more as a slasher off the bounce his stock as a draft prospect is gonna go through the roof. And depending on how quickly he develops, it could be as soon as next season. His combination of size, strength, athleticism & shooting is rare and when combined with the effort he gives defensively & on the glass, teams are going to fall in love with him as a player.
