How about rather than being an apologist for the previous owners, you look at the fact they they've appointed underwhelming managers and while they have spent money in the transfer market, a lot of it has been spent badly.
The team has been getting weaker season on season for some time now. The idea of Cullen being one of our best players would have been laughable a few seasons ago, but that's where we are now. While I certainly think Luke could improve in different areas, he has a mid-table squad in the top half of the table currently and certainly should not be considered as being in danger of losing his job, which he clearly isn't in the eyes of the owners.
