No free lunch when it comes to greens maintenance. Covers, verticutting, top dressing. Cold v hot.
In my opinion some of what has been happening this year is the poa has wilted. Many, many bent greens have lots of poa in them and the poa can't take the heat as we know. However, it appears to be able to rise like Lazarus and by Oct most places will be scratching their heads wondering if they need to replace as the poa will be thriving again. Green replacement is not in the budget at most places
