I don't really understand what you are talking about here. The last two times we changed manager almost everyone agreed both interim managers had earned the job. Prior to that we brought in Alexander who is known for falling out with people and had a decent record. Our transfer policy did change under Alexander and it wasn't spectacular but it got us the required results then he went off the boil and was looking for an exit. That's fitba.
Being Motherwell manager isn't complicated and it's not about making demands of the board. There's a budget for players, the manager needs to try and dig out a few gems, everyone accepts form will fluctuate but if you hit serious relegation form then it's out the door. If Kettlewell had just signed a few competent players on permanent deals to go into the starting 11 this summer he wouldn't be in this position. I don't think it's overly ambitious to hope for a manager who understands that starting SOD and Bair every week will get you into relegation trouble.
