Puzzle #98: National Sports (meta)

A sports-related crossword (pdf, puz, pdf solution) on Bewilderingly? I know, I'm as surprised as you are. But this one required no actual sports knowledge to construct, and the meta requires no actual sports knowledge to solve, either. The meta answer is a two-word drink which would complete the theme. As always, my email's open if you've got the answer or if you want a nudge in the right direction. Answer next week!
