Both teams are replacing key players. But Kansas' rebuild job is further along and far less daunting than Kentucky's. 
The Wildcats are likely to get better as the season progresses, but right now they are extremely inexperienced and not ready for an opponent the caliber of Kansas.
Kentucky, starting four freshmen, was exposed by Richmond two days ago losing, 76-64, as 6 1/2-point favorites. The Wildcats were 0-for-10 from 3-point range and committed 21 turnovers. Keion Brooks Jr. is Kentucky's only returning starter and he has a leg injury. The Wildcats have missed 18 of 26 3-pointers on the season. 
Kansas had a good test in its opener falling, 102-90, to top-ranked Gonzaga. The Jayhawks rebounded to beat Saint Joseph's, 94-72, this past Friday. Kansas showed good depth in that game. Christian Braun and redshirt freshman point guard Dajuan Harris were sharp in that game. 
The Jayhawk are ahead of the Wildcats right now. Kansas has shown offensive efficiency while Kentucky's defense and outside shooting have not been impressive.
