I don't agree.
While it takes 3-6 weeks to fully acclimatize, and competitively, you're never really going to be the same as at sea level, the real danger here is altitude sickness and that's what the team is avoiding, rather than going for as much acclimatization as possible.
A week makes a huge difference in avoiding altitude illness.
I don't really subscribe to the philosophy that getting there within 24 hours really does anything. The first night for many players is going to be sleepless, and the rate of dehydration is going to be much higher as the body hasn't adjusted to the lack of moisture at that altitude. It's going to think it's still at sea level and process water just as fast, rather than start conserving.
So what we'll see is the Raiders probably get off to a fast start, or keep up with us for one half at the most, and then hit the wall and nosedive as players quickly get dehydrated and/or start gassing.
I'm expecting this will be a game of two different halves.
