Interesting way to look at it.
Oddly, Seattle could mount a 4 goal comeback--In fact, IIRC, they are the team to win themost matches from a losing position this season, so they won't just be phoning it in this week, they will be on an all-out offensive at home. RSL may have lost Olave and Borchers, and that is 2 BIG loses for them if they can't carry on; especially when they have to play keep away at Seattle. I'm not certain who will win this, but I think RSL will hold on. I'll call that game 3-2
A 1 goal game for NJRB is not the absolute end of line with the talent they do have on the squad, and with Juninho out for that end of match fracas with with NJ players (and NJ only out Marquez), it is still anyone's match here--but I still fancy the Gals to move on. 1-1 or 2-2.
Philly is done. If they couldn't get it done in Philly, they weren't going to get any momentum going. They go to Houston and lose 2-1, Houston moves on.
Colorado is the same as Philly, but they looked worse (and not like the 'defending champions'). They go to KC and lose 3-1.
