Last time Bears played in London we lost to Raiders. The only visit prior to that was a win against the Bucs. Bears had most of the support each time but that was easily the most one-sided of the three.
Did feel a bit sorry for the Jags in that respect as they make the effort to come over every year. I think that's what a lot of the "fuck Green Bay" chanting was about, showing it was pro-Bears rather than anti-Jaguars. Imagine Jacksonville will be better supported next week as the "home" team.
