Boulder, Colo. • Maybe Askia Booker walked. Maybe he didn't.
At Kansas, the debate about a last-second loss to Colorado in December will be long forgotten by March.
Then again, if the Jayhawks don't pick things up a bit, they may not be playing too long in March.
"We're not playing very good," Kansas coach Bill Self said after the sixth-ranked Jayhawks fell 75-72 to Colorado thanks to Booker's 30-foot game-winner at the buzzer.
"We're not playing good at all. The pieces just aren't quite fitting yet and we're trying to find ourselves."
Instead, it's the Buffs (9-1) who are finding themselves winners of nine straight while Kansas (6-2) is looking for answers following its second loss in the past eight days and its first to Colorado since 2003.
"I'm concerned because we're not playing very good," Self said. "I'm not concerned because I know it's a marathon, not a sprint."
Kansas overcame a deficit of nine midway through the second half, then another six-point deficit over the final 1:44 a comeback capped when Perry Ellis hit a shot to tie it at 72 with 4 seconds left.
But after a timeout, Buffs forward Xavier Johnson squeezed an inbounds to Booker, who dribbled to center court, took two long steps and launched the shot from 30 feet. Nothing but net.
