Based on their prep school highlights, Kris looks to be a bit quicker than Keegan. He may have a bit more ability driving to the basket because of it. Interestingly, Kris averaged .7 more blocks per game than Keegan. He also looks to be a guy who is a real pain in the ass to keep off the offensive glass.
On the downside, Kris doesn't look to have the mid-range game Keegan does or the turnaround jumper. Early in his career at least, I think Kris will be a 3-and-D kind of a player who has to at least be respected off the dribble. If he can shoot the 3 at a good clip, he will be a really nice piece.
With Keegan, Kris, Patrick and Sandfort, Iowa is going to have some long, skilled forwards to build with.
