United have continued to have an up and down season since last the Rapids met them earlier in April. For every game where they're beating the Sounders 2-1 or Toronto 3-0, they have a game that they drop 4-1 to Houston or New York. This is clearly still a growing team that has a lot more talent than they did last year, but are struggling to put it all together.
Obviously United have some offensive skill, and it's all revolved around US Men's National Team striker Charlie Davies. The newbie to DC has made an early case for the golden boot, with 6 goals so far. Ageless striker Josh Wolff and last year's rookie of the year Andy Najar joins him in the now potent offensive attack, with a couple assists to his name. The defense is still a bit patchwork with two rookies starting on a lot of games - Perry Kitchen at center back and Chris Korb at left back - and a leaky league worst 17 goals allowed.
Colorado has only won a single game in RFK stadium since 1999, so this might be a wash either way.
