It's an opportunity if we figure out what to do with it, for once.
The more I think about it, the more I like your 'write the checks for two young, proven goalscorers and Everloan some depth next season' idea, provided we can attract players of sufficient quality with the funds. The sales pitch is simple: playing time and attention paid to the player's influence in the Prem. Then, we patch up the depth problem next summer with young players.
All the pieces of real consequence are tied down for once, so this is the moment to fix the goals-for problem. We need to replace Richarlison's contribution, and buy a striker that can play as the lead and as a second striker, depending on DCL's fitness and form. Done right, we should land somewhere between midtable and comfortably up next season. We then plug some holes with developmental talent the next summer, extend the right contracts and paper over any remaining cracks with loans. That should put us in position to complete the squad the next summer using the revenue bump from BMD.
Of course, if the players don't deliver in the next two fixtures, all of that goes right out the window.
