Constructor's CommentsI think this "playing surfaces-to-verbs" theme was one of the first I ever came up with, back in 2011 or 2012. I found it sliding around in the bottom of a filing cabinet and decided it deserved a second look. David wisely DQed a fifth themer that used pitch, since it's more of a Britishism for a soccer field. These were the four that remained.
Looking again at the fill, I may have gotten a little too cutesy with the two-word phrases WHAT IF, KIND OF, LESS SO, and SING OF, but it's hard to say. Maybe two out of four would have been better?
