With regards to the article, the schools that are giving such rich buyout payments can afford to do so. They have wealthy donors, and those donors will definitely have quite a bit of say so when it comes to how the Board of Trustees make decisions, even if it's indirect influence.
For these guys, it's going to be one of two things. Either find a coach who you know is all but guaranteed to be consistently excellent, or take a gamble on a less proven commodity and don't give him the option for a huge buyout.
Schools that don't have the donors simply aren't going to be able to offer such contracts to what they perceive to be top tier coaches, so they're most likely not going to have such problems.
