Drive up to Plucker's or Bikini's in San Marcos. The one sports bar in New Braunfel's closed but I think they have TV's at Applebee's down there. Other than that, I couldn't say.
Wings and Rings in New Braunfels has great food & lots of tv's. And Seguin has The Ticket across from the courthouse. I haven't been there but it looks pretty popular.
