Yes because the Jags are building a new stadium and the NFL wants to see if it is plausible for the Jags to play home games in London while staying there for either the entire first half or back half of their schedule.
Ie, how big of an advantage would it be for the Jags to play all 8-9 home games there in a row at once, then play all their road games?
As he saw after only one week of them being there, a pretty big advantage.
