They will definitely win 3, and have a chance to sweep 4 with the Bengals at home.
When I looked at the schedule prior to the season, I thought they would be lucky to be 2-2 at this point. They lost to the best team in football and a team most likely to win the NFCE. After this letdown, they will be pumped up to beat Tenn, and they will be motivated as a home underdog against the Bengals. They will beat the Jags in London, but then I would worry about another letdown against Miami at home, especially if they are 5-2 heading into it.
