Hello Kyle,
Based on your images - I do think that there are fungal and brown patch issues. It sounds like there are even some insect issues too. I don't think the problem could be a non-disease problem like irrigation issues, heat stress, pesticide damage, or compaction
I recommend you get a confirmed diagnosis from the MSU Diagnostic Plant Lab - Please send your images to the MSU Diagnostic Plant Lab. The lab strongly encourages clients to email digital images prior to bringing or sending physical samples. Images can be sent to <personal data hidden>. There is a $20-25 dollar fee. Their website has the form and instructions: https://www.canr.msu.edu/pestid/
When you are ready to send a sample - Details of submitting a sample are at this link: https://www.canr.msu.edu/pestid/submit-samples/
(Please make sure you read their important notice to their clients)
Residential Turf Sample
Include a square of turf from the margin of the diseased area so that both healthy and diseased turf is included. Minimally, the turf square should be 6 inches x 6 inches. An intact layer of soil should remain on the root system. Wrap samples in newspaper and pack them in a box for shipment. Do not add moisture to the turf prior to shipment. Provide a detailed description of cultural practices (irrigation, fertilization, pesticide application, etc.) and images of the symptoms in the lawn with the sample.
