I'm a little late posting this with the LA vs Chivas USA game already kicked off (and LA up 4-0 right now). But here's a look at what we want to happen.
Chivas at LA
What we want to happen - Chivas win
This ain't happening, as I said, still in the first half, LA is up 4-0. LA getting a win would put them just 3 points back of KC. With all the teams between KC and LA though it's unlikely to matter much, but finishing ahead of LA is good for potentially hosting MLS Cup.
Portland at Vancouver
What we want to happen - Vancouver win
Portland winning allows them to jump over KC in the Supporters' Shield race. Having Vancouver pull off the win at home to keep their slim playoff hopes alive would also help KC in the race for the Supporters' Shield.
