Based on what I have observed (NOT in person):
He seems to be somewhat less athletic than Zeke, and does not jump as high. He does not have as much wingspan.
However, he is much more aggressive to the basket than Zeke was as a freshman. He is not blocking out effectively yet, but he is a big body, as compared to Zeke who was described as "long and thin".
I think as a Junior (third year player) he will be a monster in the middle. He may get less blocks, but I think he will score way more points. I think down the line he will also be less prone to having the ball taken away under the hoop, as Zeke as never been a great ball handler.
All of which is NOT a knock on Zeke in any way shape or form. Just my take on where Pat is now, as compared to where Zeke was as a first year player.
