Howard, Donovan and Dempsey are our three best players right now (Michael Bradley would be in that list of late). Of course we rate them (and not everyone does, come on now). Howard ranks among our best keepers, LD is the best player in our history, and Clint is #2 (though some have those reversed).
How rating them is a surprise to any of you I don't know. Pick England's three best players - most people support them. Hart, Rooney, Baines... (however you rank your three) You support.
But to say we only support them in the PL because they are American is ridiculous. They actually are top performers with a long history. Or else we'd be on here saying we should be in for Jozy Altidore because he had a hat trick the other day.
Our top 3 are in a different league than our other players. You'll see the Yanks providing balanced perspectives on other players - an example being Geoff Cameron, who has been spoken about here. Tim Ream. Stuart Holden.
We talk about the big three because two of them played/play here, and one of them came close to playing here.
