Bradley is clearly the best American player right now. In fact, he might already be the best American player of all time. His skill and creativity are way beyond anything else on the USMNT. Reyna was special before they slowly chopped him down in the brutish Scottish league, but I don't recall seeing him play better than Bradley is now. I saw Bradley's talent years ago, it is scary some actually thought it was nepotism that secured his role on the national team.
I don't want to sell Dempsey short who also demonstrates real skill at times. However, it is his ability to finish that sets him apart. An attribute that is sorely missed from the national team when he is absent.
