Colorado at No. 9 Kansas

•  WHEN/WHERE: 1 p.m. Saturday at Allen Fieldhouse in Lawrence

•  TV/RADIO: ESPN2; KCSP (610 AM)

•  ABOUT COLORADO (7-1): Colorado coach Tad Boyle, a Kansas guard in the early 1980s, has the Buffaloes moving in the right direction. After an NCAA Tournament appearance last season, Colorado posted a victory over Baylor on Nov. 16. Still, the Buffaloes needed two overtimes to beat Texas Southern and lost at Wyoming on Dec. 1. Kansas will need to find a way to slow guard Spencer Dinwiddie, who is shooting 54 percent from three-point range. Kansas will make a return trip to Colorado next season. And with just one senior in the starting lineup, they might be even stronger next season.

•  ABOUT KANSAS (6-1): Senior center Jeff Withey’s block-to-foul ratio has become an early-season curiosity. Withey leads the country with 40 blocks while committing just six fouls in seven games. The Jayhawks continue to struggle from the three-point line; they’re shooting just 29.9 percent and only Elijah Johnson is shooting better than 35 percent. The Jayhawks, though, have been one of the best defensive teams in the country, holding opponents to just 35.3 percent from the floor. Amazingly, teams are shooting better from three-point range (35.5 percent) against KU than two-point range.

•  BOTTOM LINE: This could be Kansas’ toughest home test to date, a potential NCAA Tournament team with some offensive weapons. Elijah Johnson and Ben McLemore will need to be at their best offensively, but Withey’s presence — and KU’s defense — make the Jayhawks a solid favorite on their home court.
