MLS playoff roundup and predictions

Catching these four match-ups in the middle, so each will be half analysis/half prediction...

Seattle Sounders FC v. Houston Dynamo (0-0 aggregate)

After tying 0-0 in Seattle for the first leg, the finale will take place Sunday. The story of the first game was 90 minutes of physical brawling, I think the second leg will be the opposite: some entertaining soccer.
