Week 5 of the league's 20th season, and Spencer and Billy are renewing one of the more lopsided rivalries on the books — 17-8 in Spencer's favor across 25 career meetings. Billy has cracked him in the playoffs before, though, and that 2016 nail-biter (a 1.36-point swing) is exactly the kind of thing that lives rent-free in a guy's head for a decade. Whether this is the week Billy starts chipping away at that deficit or Spencer pads it further is the whole question.
