This is a "must win" for both teams.
HOWEVER....whoever loses will still be in the group of 6 to 8 teams from which the eventual SB winner will come from.
Also.....the common belief that everything is based on their rushing attack is a bit off: they have mainly relied on the pass recently...and against Wash Hurts just stayed in the pocket on his own accord.
Their secondary has been ravaged by injuries .....
If I'm Dallas coach...I still keep a balanced attack even if rushes are unsuccessful, as you can't fall into their trap of being 1 dimensional....but WHEN you pass make it quick timing throws in middle of field
That said, this is an imperfect league right now with no real powerhouses....so in that context they are a very good team that knows how to win (they've lost like 2 games in the last 12 months or so they TRIED to win with their QB and starters in the game....Jets and the SB)....but so are we.
Might as well just grab a coin and flip it to predict the winner of this one
