DC won the first meeting 18-6, but Vegas led that game 6-3 heading into the 4th quarter. The Vipers backs are against the wall at 0-3 and the Defenders have to be feeling good about their 3-0 record.
Outside of these teams' first head to head meeting, both Vegas losses have been by four points or less, and the Defenders wins have came by six and four points.
Expect Vegas to give their best shot on Sunday and cover.
