The 21-year-old junior forwards for the Kansas Jayhawks — sometimes called by the pseudo-plural Morii — are difficult to tell apart. They are even more difficult to separate.

They have the same tattoo designs in the same places. They have identical haircuts and facial hair. They live together, drive the same car, have the same class schedule, like the same music. When one gets food, he gets the same thing for the other without asking. They even wait for each other before taking postpractice showers.

And neither can come up with anything different about the other.

“We are one,” said Markieff, often called Keef. “We’re the same exact person.”

Both said that they had made no decision about whether they would leave Kansas after this year to turn professional. But just the thought of it, of being drafted by different teams in different cities as happened to Stanford’s celebrated Lopez twins several years ago, makes them pause. They have never been apart for more than two days.

“We’re definitely not ready for that to happen,” Markieff said, adding that it would probably play a role in whether the two returned for their senior seasons.
