I think it's probably to build Gold Cup depth, while you're also dealing with a concurrent U20 and U23 camp.
There's been a kind of undercurrent at USSF of "we must re-habilitate our reputation lost in the catastrophe at Couva". The best way of doing that is putting it behind us, not playing Yedlin, gonzo, bradley in the back!!!
US have two good players out there today. Keeper and CP. throw in an accidental touch from GZ and we have a goal.
