Theme: IN THE MIDDLE (17D. Like this answer's position, and what can follow the starts of 16-, 24/51-, 38-, 60- and 69/1-Across) - IN THE MIDDLE can follow all the below green-highlighted words.

The unifier IN THE MIDDLE is easily placed in the very heart of the grid. But quite a feat to cross it with the other three long theme entries. 14's are always a challenge and you don't see them on Row 3/13 often, same with 12's and 13's.
I've yet to become a fan of split theme entries. I'm OK with 1A Across and the last Across entries to bookend the grid, even with the reverse order. But the 24/51 style split distracts me.
