Lawrence and Lincoln are the same place, except you can win 6 games a year in Lawrence and they will give you a new contract. I would stay in Kansas.
I’d add that Lawrence is a bit nicer than Lincoln, and closer to a bigger city/airport (Omaha vs KC), and KU is quite fine with institutionalized cheating (KU basketball is as dirty as they come). I do think KU is on the outside looking in re: future conference expansion and ending up with a chair when the music stops. I hear the B1G isn’t motivated by KU academics, basketball, nor the KC market. Best of luck in an even more second-tier Big 12, Kansas.
