Blaming him is pointless though. All he's doing is what the owners want him to do. People act like he's single handily making these decisions. He will always do what the owners tell him to do, period.
All the NFL and it's owners care about is making more money, blame the owners. Hell, Kraft is one of the guys who really wants the NFL to have a team in London.
As for this, yeah, this sucks. A lot of people are going to be screwed adjusting their schedules to make sure they're able to catch a game only to have it changed the week before.
