Go to this link to play around with weeks 15-16-17 scenarios to determine NFC West division winner.

You don't have to click all games but only teams in NFC West games.

Basically 49ers win all tiebreakers possible if any team finishes tied for 1st place, so just because of the difficult schedule of the remaining NFC West teams, we can afford to lose either against SD or against St.L. and still have a mathematical chance (if we win 2 of 3).

In week 15, the only way we are officially out of the playoffs is if we lose, AND Rams win AND Seattle wins.  It will be unlikely that our hopes will end by the end of week 15!  Pretty much this means still lots of chances to make the playoffs...

Have fun with the ESPN playoff site...
