I think not. To be perfectly honest, it could be a good thing for a lot of reasons.
Focusing on a sellout streak is pretty ridiculous. Has very little to do with what goes on down on the field, which is what ultimately matters. And you really can't say that the team benefits from a stadium 2/3 empty even when its a "sellout".
Finally we have to be concerned about actually watching a team as bad as the Chiefs. I speak particularly of young football players, who need to be protected from watching these weekly piles of excrement. The ripple effect from a decade's worth of bad football is eventually going to drag football across the board down to an unspeakable level.
I therefore call on all Chiefs fans to do the right thing this week. Turn off the damn TV. Do something constructive with your family the week before Christmas. And let the Chiefs bury themselves on Sunday against Cleveland
