If Cauley-Stein plays and is near 100%, he could make life difficult for Kaminsky. Not only is he 7'0" and very long, but he is also quick. Kaminsky likes to take slower players outside and either shoot if they don't guard him closely or drive around them if they do. Stein is quick enough and athletic enough to defend Kaminsky on the perimeter, and he is tall enough and long enough to defend him on the low block.
Kaminsky has developed into a terrific player, but I have been real impressed by Cauley-Stein's defense the few times I watched him this year. If Kentucky does not have to give help on Kaminsky, they can concentrate on not giving Brust, Dekker, and Jackson open looks behind the arc.
I also think the size and strength of Kentucky's guards, the Harrisons and Young, will give UW's guards some problems when they attack the basket.
Finally, I think Dekker will be eaten alive if he tries to guard Randall. Hayes might have a better chance of preventing Randall from dominating the offensive glass.
All that being said, I think UW keeps the game extremely close, and down the stretch the Badgers pull it out. The just don't beat themselves.
