Maybe the Kansas rumor is to throw them off the scent of Missouri and UVA.
If there is any basis to the KU rumor, it just means the Big 10's direct attack at getting who they want from the ACC for 14 and 15 has failed (UNC/UVa too strong willed). Plan B is to get UNC/UVa by getting the SEC and the Big 12 to start the process of destroying the ACC, or at least the threat of doing so to make UNC/UVa blink. Big 10 spreads word that the Big 10 is moving on a school regarded as an SEC target and capitalizing on the myth of current Big 12 instability.
Ideally the SEC and the Big 12 continue their reported gentleman's agreement/cooperation in expansion, giving the Big 12 a better chance to get the ACC schools that make the most sense.
