I'll just say that Gip came in as a FR with a lot more skill and touch on the low block than I was expecting, his hook is pretty reliable and he even showed the ability to knock it down with his right hand at times
As many others have pointed out, he is somewhat limited due to lacking explosive athleticism but he's already fairly crafty in the paint and if he can continue to develop that craftiness, I could definitely see him being a 12-13 and 8 guy by the time he's done at KSU.
As for Johnson, well when you've got even his HS coach who's pumping up as some sort of Kenneth Faried clone saying he has some offensive limitations, then well, I'm not going to expect much pt production from him early. Does look like he already has decent physical build and moves pretty well for his size, so he has a good base of physical tools to build from.
