Hawks46, I like all your comments, and they are very valid and very human.
The flip side of it is just on a pure statistics basis, a team that gets a first round bye and a home playoff game has a MASSIVE advantage over a five or six seed in terms of simply reaching the Super Bowl.
With seven games left, and a 1.5 game lead, and one win in hand against the 49ers, we are really in excellent shape to claim a first round bye, as well as HFA throughout, and just that simple stuff means we're huge favorites to win the whole damn thing. This would be true just historically, basically, not looking at all at the specifics of our team, our schedule, the schedule of our rivals, and that sort of stuff.
As you note, when you get into specifics, NO has to play both SF and SEA which makes it a lot harder for NO to catch up with us for HFA. SF has a tougher schedule through the end of the season, certainly. If SF manages to beat SEA in SF, that just becomes a series split, it's not a huge huge advantage for them, and there are many ways we could still win the West (better record, better NFC record, better division record) even if we lost in SF.
