I know, I just like the site to look professional! IMO, it should either be "Murray still to decide on coach" or "Murray to decide on coach after USO" - not both together!!
Well, we already knew that he was going to wait until after the US Open to decide on a coach. The headline arguably wouldn't have made as much sense without the "still", since we're reporting on something that had the potential to expedite the process. So despite the offers he has received, he "still" plans to wait.
I wouldn't have a problem either way, but I can see why Mark put it the way he did.
