FWIW, a media article addressed this exact issue and compared it to John Calipari going from Kentucky to Arkansas.Those were all either laterals for more money or steps up IMO
Calipari's Wiki page says this:
2019–24
In April 2019, Calipari agreed to a "lifetime" contract with Kentucky, centered on a 10-year coaching extension, and a lifetime paid ambassadorship when he retires.[28]Following a first round upset loss to the Oakland Golden Grizzlies in the 2024 NCAA Tournament, Calipari announced he would be leaving Kentucky, but did not immediately announce plans to retire or accept another job.[29]
