It doesn't surprise me that some one is trying bermuda in Delaware.
Delaware is squarely in the transition zone, the hardest place to manage turf in North America. The cold winters are less than ideal for bermudagrass, but the hot, humid, summers are perfect for fungal diseases, that put a real hurt on the cool-season grasses like bentgrass, ryegrass, or bluegrass.
Fungicides may control the disease, but only at a huge cost, especially for large areas like fairways.
Add to that the infestations of summer weeds like crabgrass and crowfoot, the odd infestation of insects like grubs and cutworms, not to mention heat and dorught stress and wilting, and I can appreciate that it is an advantage to have dormant, brown bermuda turf in the winter in order to get some sleep in the summer.
