This lineup will test even the most enthusiastic Briton’s patience.

The Jaguars have become a virtual home team for London, and they will play a game there for the fifth consecutive season. That may be in part because they have not had a winning record since 2007. At 2-11, they are staggering to another disastrous year. The Jaguars have been rumored to be the team most likely to move to London if the N.F.L. decides to put a franchise there.

Their opponents, the Ravens, at least have a winning record. But after losing to the Patriots on Monday night, the Ravens are uncertain for a playoff spot. Next fall is a long way away, but right now this quarterback matchup would be Blake Bortles vs. Joe Flacco.

Perhaps the most unpredictable game on the London schedule is Saints-Dolphins. After a run of mediocrity, the Dolphins have sprung to life this year at 8-5, although the playoffs are by no means secured. The Saints, expected by many to bounce back this year, are a sad 5-8. There is no telling what these teams will be like come September.

The Cardinals have been one of the season’s biggest disappointments, slipping from Super Bowl contenders to 5-7-1 afterthoughts. Carson Palmer will be 37 next season, so it is hard to see a huge improvement. But at least they are not the Rams: 4-9 in their new home, Los Angeles, having just fired their coach, Jeff Fisher.
