1) Was Boca's injury serious?
Looked like a strained hamstring. They probably just pulled him as a precautionary measure.
2) How did Klinsmann and Jozy interact in the game? Open hostility or dismissiveness? Relatively normal?
Well Klinsmann gave this quote about Jozy in the postgame press conference.
I think you saw Jozy Altidore today was a handful. He gets a big, big compliment for his performance.”
3) How was Aguedelo other than his assist?
He looked lively much more involved than his past performances with horrendous Chivas USA. He may be an interesting option as a winger in a true Dutch 4-3-3, than as a center forward. Unless Jorge Vergara does indeed instituted sweeping positive changes at Chivas USA, I'd hate to see Agudelo's development stagnate at a terrible club. One of Hans Backe's more puzzling roster decisions at RBNY this year was to trade Agudelo for nothing.
