I hate these overseas games. But, since we're stuck with one, I personally like the fact it's relatively early in the season when the team is still fresh. As the season wears on, any extra travel has to be a nuisance.

Panthers restricting ticket sale to U.S. residents.
I always find it a bit off-putting when playoff teams try to limit visiting fans. It's sort of moot as well since there's so many secondary ticket sale options.
