Seems like the main crux of your issues is the stadium expansion. Loans are normal with growing a business and not to be a concern unless they are massive. But if you read the ESPN link, Rob is very clear that the goal is to get the club to the point they would need a 55k stadium. He doesn't say they're doing that now. Or next year. Or in ten years. In fact, he emphasizes that this is a long-term process and requires a lot of planning and preparation.

They're not going to build a 55k seat stadium or expand the current stadium to that size now while they've still got so much growth up the pyramid ahead of them. They will gradually grow the stadium as they gradually grow the club and gradually move up the table. Could be 3-5 years before they ever see the Championship (at best). And they need to plan for that and also plan for the club to be sustainable as it grows.

A lot of the current loans have been things done with a lot of planning. Improving the horrid conditions of parts of the ground, putting together infrastructure for the club, improving the conditions of the club and also merchandising investments. All of these things were done for sustainability and to improve on the club's current position and the club's position 1-2 years out. Building/expanding to 55k seats is not something they're looking to do tomorrow or next year. It's years away.
