Not taking sides of whether to over-seed, or not, but ryegrass gets a lot of undeserved blame.
Many, many years ago, when I was a super, I used to overseed in NC with rye on fairways, tees and greens(also included poa trivialis). The greens would get so fast in the spring, I’d have a hard time keeping approach shots on the greens….because those balata balls back then would zip right off the front.
Fairways? Nice and firm….because there was zero fairway irrigation….not because I wouldn’t, but because there wasn’t any system in place.
So, bemoan overseeded conditions all you want, but please, quit blaming the grass.
