It was only his worst game since Kansas. Hasn't been that long. Good defensive teams no how to take him away from what he does best. Creates a huge problem for ISU's offense because so much depends on him. Bolton had a lot of problem too when he tried to drive on Baylor whose guards for the most part are able to stick right with him.
Also, ISU must really not be coaching on how to find guys and box out. When you don't box out the best rebounder on the court in Vital, it is a problem. But with that being said, the refs let Baylor really push and shove underneath the basket on rebounds. Not only that but it seems this year that refs are letting a lot of physical play go in games, I know Bilas has mentioned this in columns as well as on broadcasts that the whole 'freedom of movement' emphasis seems to have gone out the window this year.
Also, Prohm needs to completely scrap the two big lineup with Jacobson at the 4. It doesn't work... move on, coach.
