That's probably an understatement.
As for the "oil money" who's to say Rovers wouldn't have received any? If Jack was still alive he probably would have seen the "writing on the wall" with Abramovich (butterfly effect here I suppose) and become open to a sale. He wouldn't have neglected the sale process and sold to people who don't know what relegation is. Of course that's all the fault of Anderson not the people who trusted him enough to look for a buyer. If "trusted" is the right word because that implies they actually gave a toss.
I think Kamy said Williams warned him about Syed. Perhaps Williams stood up to the Walkers on that but thought he could handle Venkys and overcome their lack of knowledge. If Williams had objected to Venkys the Walkers may have sacked him anyway if it's correct he saw through Syed and tipped off Goldberg, etc. Either that or Anderson completely fooled him as well but nobody ever considers that scenario do they? It's always gullible Venkys how could they trust Anderson when Williams had no issues working with him until Kean got the managers job.
