I agree with you. Their defense is a little suspect though - if their opposition can keep up with them on offense (I agree, something that is very unlikely to happen), then they could be facing a scare.
WVU should be #1. Not Mizzou. Mizzou is impressive, but they beat a vastly overrated Kansas team. However, that's not to say that they don't deserve the top ranking though.
As long as WV doesn't blow it against Pittsburgh next week (the only way they do that is by getting ahead of themselves), then they'll be playing in the NC game without a doubt. I think WV is a lock, because I can't see them losing to a Dave Wannstedt-coached Pittsburgh team.
However, their opponent should be interesting. Mizzou is definitely worthy of being where they are at this point. If Oklahoma beats Mizzou next week, should Ohio State, currently #3, be their opponent? No. God, I hate the BCS.
I would kill for a 10-team tournament, with #s 1 and 2 getting byes. I'd prefer that 3 or 4 teams gripe about getting shafted from a 10-team tournament than 10-15 deserving teams getting left out of the national championship game.
